This usually occurs between two drunk as fuck individuals on a friday night. The qualifications are that you fuck three and only three times, that you have just met and that the female has trouble walking the next day. Anal sex qualifies as well but be careful you must know what you are doing.
College student 1: Man that was one crazy friday night fuck fest
College student 2: Why what happened bro?
College student 1: O u know just railed the shit out of this broad three times.
College student 2: Nice man i will have to try that soon.
