The male art of masturbating whilst perched upon the
toilet taking a dump. Key
words here are "Fap" (
Masturbate) and of course "Shit". Also, the past pretense of shapping may be referred to as "To have just shame".
"Daaamn, did you hear about
Rick in the bathroom?" "Nawh
boss, what happened?" "He was taking the biggest shap in life!" "GROSSSSSS." AND "Bro, I think i just
shame." :\
