A name typically seen in the boarda of 4chan. A coomer is someone who is addicted to pornography and masturbation to the point where their whole life is affected by it. Coomers' life orbits around excessive masturbation and often affects their personal relationships.

Typical American newspeak designed to shame males. By it's own definition "only pleasure in life is ejaculating to porn several times a day" a female can't be a coomer. Lesbian and violent porn which are predominantly consumed by women, 50 Shades' international success and being the top customers at sexshops clearly don't count in the eyes of these soy-filled misandrists.

Initially an internet version of the Wojack guy, a Coomer is a male chronic masturbator, an Incel on steroids, who lives in front of his PC consuming porn all day, and having no other interest in life other that to reach his next orgasm.

But the meme has grown, naturally.

Coomer now refers to any young man who is solely concentrated on an almost psychopathic need to chase the next dopamine hit, be it masturbation, game score, high of any kind. Coomers are now utterly useless self-pleasuring addicts, to the exclusion of any future career development or frankly any future plans at all beyond the strict need feed their addictions.

The idea that porn is the sole purpose of ones existence and that usually people under this ideology usually tend to beat their dick like David Pelzer gets ragdolled by his mother.

A coomer, (Pronounced COOM-er), is an elusive creature that spends its whole life desperately trying to reach the next best nut. It is classed as a critically endangered species. The coomer was once thought to be nothing but fiction due to the rarity of these beasts.
Not much is known about the habits of these elusive creatures, but they are said to reside in tiny rooms that reek of mildew and B.O., floor littered with custom-made waifu pillows and the coom of the coomer itself. They are said to be mostly solitary, though there have been half a dozen cases of supposed coomer packs being sighted in the wild.
It is said that, if disturbed, the coomer will become enraged, and will attack the offending creature. It has been reported that a coomer may even coom upon its enemies, some say even stuffing them into homemade COOM jars on occasion.

A man, typically in his 20s, who's sole existence revolves around Cooming.
