Usually found at WTF, Welcome to Facebook, is a term first designed by Mark Zuckerberg himself. He made this shortened word to explain to people, "Facebook IS something different!" Give or take a few weeks, and people had turned its common use on facebook for bad. Thereby, turning..WTF... to What the Fuck, instead of Welcome to Facebook.
Dude1 - "Hey, where's Bob?"

Dude1 - "Yeah..... "
