beat your chick day

Beat Your Chick Day (B.Y.C.D) is a commonly used abbreviation in the (mostly African) suburbs. It is on 13 November, and it is used to legally beat up your chick... However, if the chick has wounds the next day, it isn't legal, the criminal must be turned in. Thus you might not have heard of it before.

Beat Your Chick Day:
'Jordi, you beat up your chick really fine man!'

' Did you know that B.Y.C.D is tomorrow?'
