Underwear of Turin
When you put your underwear on after a sex without cleaning your genitals and leave an image of your junk in them. Then you use them to prove to your friends that you got laid.
Mike: Hey Benny, can you not leave your Mike: “underwear of Turin” on the bathroom floor, no ones impressed that you got laid last night!
Benny: well you should be, it was your Mom!
Benny: well you should be, it was your Mom!
