Ball your fist up, and lightly "bop" the
bottom, or
soft part of it, on someone's forehead after saying the words, "Ball up!" it's a verbal and physical response to someone who fails/messes up/is just plain wrong/ or does something stupid when trying to make themselves look cool or smart. Some
people even say, "bink!" while simultaneously applying the forehead bop.
"Boise State deserves to
play for a National Championship."
"
Ball up!"
"I tried to get that chicks number, but she told me she'd rather swallow gasoline than continue the conversation..."
"you get a FRESH
ball up... Bink!"
