Dude2: Yeah man, I want to respond with my SnapChat id but I can't from here.

Yik Yak

A social media app where you're completely anonymous and can chat with people in your area. Usually it's used by teens for bitching about people at school, spreading gossip, and the occasional stalker talking about how hot so-and-so was that day. Because the app has rules against naming people, you'l often see pitiful attempts to cheat this by listing the persons initials when the shit talking starts.

Guy 1: "Damn, did anybody else see M.F's ass today in the hallway? I got like so hard. Too bad she's dating that faggot T.B"
Guy 2: "Wat"
Guy 3: "Dude, stfu. You're gonna get Yik Yak banned from our campus!"
