The philosophy of life and sexual relations, where after banging
a female, the male proceeds to kick her(usually metaphorically). Kicking can refer to actual physical abuse, but in most situations simply means abandoning said woman. Proponents of this philosophy say that if eliminates many of life's problems. This process is meant to be applied to "stupid bitches" when the man does not want any more contact after the act. Often shortened as BK. See also hit it and quit it
and hit and run
Joe and Karen made sweet love last night, but since Joe is a strong advocate of the Bang and Kick theory, he expelled Karen from his apartment shortly afterward.
