FetusDestroyer's definitions
A 9/11 is a sex act in which a man violently and unexpectedly inserts his penis into the anus of his sex partner. This may occur during or outside consensual intercourse.
When I asked Maria why she broke up with Stanley, she said that he gave her a 9/11 after a night of drinking.
