gaybaby is a slang for a prolonged awkward silence in conversation. It originally was from a pop culture reference that during every awkward silence a gay baby was born. (Adapted from "Its a wonderful life" pop culture reference "teacher says every time a bell rings an angel gets its wings"). Because of this, kids in the 90s and early 00s would race to be the first to exclaim "GAYBABY!" during an awkward silence. Bonus points awarded if it was done in class after an especially awkward silence that follows the teacher scolding a classmate.

Guy #3 "GAYBABY!!! HAHAHAHAHA!"
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.
