When you stick your cock up a girl's ass (or keister) without asking her. Then, she gets angry and says stop but you continue for at least 15 more seconds until stopping. Then, you pull-out and say Pardon My French.
Pardon My French Guy 1: I stuck it up this girl's Keister last night it was tight! She must have wanted me to stop cause she was screaming stop!!!! But i did'nt stop right away i kinda ignored her for 20 seconds or so.
Guy 2: Sometimes you gotta go with the flow and just stick it up the poop shute.
Guy 1: Ya, i know what you mean. I hope that she can Pardon My French.
