When your about to blow your load from getting a girl in the ass, repeatedly bigin donkey punching her until her ass can't get any tighter and it is nearly impossible to get your dick to pull out.

George: Sounds like she reached titus maximus; she's gonna have head trauma and ass problems for a month.
