Ghosting is an online term that can have at least two meanings

First:
Ghosting can mean the viewing of a stream/streamer for the purpose of gaining information that could be used to gain an advantage against them (no matter if they're a team or an individual)

Second:
Ghosting can mean the shutdown/ceasing of communication with someone without notice. This can include but doesn't always require the closing or shutting down of social media accounts or ports of contact such as email addresses or phone numbers.

The act of suddenly ceasing all communication with someone the subject is dating, but no longer wishes to date. This is done in hopes that the ghostee will just "get the hint" and leave the subject alone, as opposed to the subject simply telling them he/she is no longer interested. Ghosting is not specific to a certain gender and is closely related to the subject's maturity and communication skills. Many attempt to justify ghosting as a way to cease dating the ghostee without hurting their feelings, but it in fact proves the subject is thinking more of themselves, as ghosting often creates more confusion for the ghostee than if the subject kindly stated how he/she feels.

When someone ignores your text, email, or other message on one platform while they received it and are online and active and on another with the intent of you not knowing it. This applies to anyone not solely someone you were dating. Seeing a read receipt in a text but getting a 'snap' from them the same hour. Getting a Facebook like or IG like after they ignored your text. Seeing them update their status or online on FB messenger without responding. The act of them avoiding you in their most direct form of communication while they are still active on less direct forms.

The act of suddenly ceasing all communication, particularly electronic communication with a specific person, and it usually involves the "ghoster" completely blocking electronically the "ghostee" from being able to communicate with them. The "ghoster" usually does this to the person that they are dating and/or romantically involved with, but no longer wishes to either date and/or be romantically involved with. Ghosting is done in hopes that the ghostee will just "get the hint" (i.e tick tock) and leave the ghoster alone, as opposed to the "ghoster" communicating their true feelings in a manner akin to an adult. Ghosting is not specific to a certain gender (although females engage in the behavior more than males) and is closely related to the subject's maturity, communication and ability to deal with conflict skills.

Ghosting is the providence of emotional, behavioral and situational cowards. Ghosting is the operative, almost default behavior of choice for conflict avoidant/conflict adverse/self-absorbed/self-centered/selfish people because it is easier to "ghost" than to deal with conflict. It is easier to blow someone off than to do introspection. Whoa, that's way too scary for ghosters.

When a guy seems really into you then suddenly disappears.

While at work,
The act of doing nothing and being hard to find.
Also said as: to ghost, ghost, go ghost

when you take a shit so massive and with such velocity behind it that it forces itself to "disappear" down the toilet tube upon hitting the water, prompting a confused state when you look into the bowl and find it nowhere to be seen

Ghosting is a verb that requires no action. A noun for nobodys. And an adjective most suitable when describing a person that is rude and lacking courage.

When one is ghosting another they abruptly and unexpectedly stop communication. The ghoster may have legitimate reason to stop communication but lacks the courage to share with the ghostee what those reasons are. And probably the more common cause of ghosting within the dating community the ghoster and "roommate" were able to smooth things over. Ghoster figures the cost of good laughs, good sex was far less than the cost of child support. Ghoster does not wish to be honest & forthcoming concerning details of ones life. The ghoster can show interest, seem infatuated and just one day later show no interest, no reply to text/calls, selecting ignore so notifications will not be received from said ghostee. From a ghostees perspective there are now questions unanswered and in a quest to find answers ghostee will send at least one more message just in case there had been no ghosting at all. Surely ghosters phone had accidentally been submerged in water during last weekends fishing excursions. And surely ghoster was able to replace it by now. When still no reply is received ghostee sends a passive "take care" message and excepts the relationship is dead!!

ghoster should be treated as if they no longer exist if they try and spark up conversation or relationship in the future.

When someone you (consistently) talk to suddenly stops responding without notice. Their goal is to end the relationship without hurting the other's feelings but it ends up creating more confusion and frustration. Often utilized by immature jerks.
