A force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions! As discussed in Lesson 2, some forces result from contact interactions (normal, frictional, tensional, and applied forces are examples of contact forces) and other forces are the result of action-at-a-distance interactions (gravitational, electrical, and magnetic forces). According to Newton, whenever objects A and B interact with each other, they exert forces upon each other. When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is

A provoked outburst, following piss-taking by friends.

œ‘‹›ˆü—´Œ?'s most famous gayass.

n: the act of getting two girls into the precarious situation of being naked, while allowing a male (usually a Kyle) to piss into the first girl's vaginas, then, once full, the piss will leak into a funnel which is attached to a tube that has the other end inserted into the second girl's vagina.

When the second vagina is full, a second funnel and tube is used to transport the piss to the first girl's asshole.

Once full, the mixture should leak into a third funnel and tube which is inserted into the second girl's asshole.

This leads to a fourth and final funnel and tube which leads to a beaker glass to allow the solution to settle.

The girls then take turns drinking their special concoction.

Literally the stupidest thing to grace the Internet. Some attention starved asshole gets the bright idea to record his/her ugly face watching a YouTube vid or, god forbid, a 20-40 minute episode of something and expects us to sit there and watch them make facial expressions or some shit. It's literally watching a video of someone watching a video! Their face takes up 80% of the screen and the thing they're watching is usually miniature and in the corner. It's a pathetic fad that needs to die very very quickly. Newsflash people: NO ONE CARES WHAT FACIAL EXPRESSIONS YOU MAKE OR WHAT STUPID SOUNDS COME OUT OF YOUR MOUTH WHEN YOU WATCH SOMETHING!

A fear reaction that comes from terror rather than surprise. Typically defines an increased body temperature and slight shaking of the hands, but none of the typical symptoms of fear (such as an increased heart rate or breathing faster.) Named for Junji Ito's Uzumaki manga, which is probably one of the most well-known things to cause this reaction.

A reaction status is a Facebook status posted purely because the person posting it is aware that it will have a reaction (a large number of comments/likes)

A common 'reaction status' is seen after a popular TV show, when people post funny lines from the show knowing that people will be logging into Facebook shortly afterwards.
