Often used in Halo 3, "getting beasted on" is when someone who is "beast" (pro or legit) owns the living crap out of you and pretty much embarrasses you by making you look like a n00b. This term is originally derived from the term of "getting pooped on," which is to lose a gamepretty bad. The difference in getting beasted on is if this happens to you despite you having some measure of skill. Talking yourself up as pro just cause you're a level 50 and then getting raped 50-7 where one of your opponents gets 30 kills on your team is a textbook example of getting beasted on.
We thought we were good until MC Hellraiser beasted on us. We lost 12-50 and he got a 19 kill perfection on us. He screamed at us to get beasted on when the game was done. Now I wish I hadn't talked so much shit cause now I look stupid.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
