look up any word, like sex:
Where your chest sticks out all flat and gross like.
Tommy: "Hey why's Emily pushing her chest out like that?"

Billy: "Dude, she's not. She's got that nasty pigeon chest shit going on."

Tommy: "OHH. AH SICK!"

Emily: "Caaaaaaaaaaanada!"

Billy: "Ah, disgusting, I didn't know people like that could talk."
