look up any word, like bukkake:
 
1.
greeting/acknowledgement used by members and associates of the 21st street coop.

when you see a motherfucker outside of the house, it is customary to greet them by shouting "boner in your butt!" at them as loud as you can.

this is done best from a moving car or where there are large crowds of people around (at the intersection of guadalupe and 21st for example.)
"Boner in your butt, Dave!"

"Boner in your butt, Brett!"

"Boner in your butt, Officer"
