When you fuck three different virgins in a year's time. After you fuck a virgin, the clock starts, and you have exactly one year back until that day to fuck two other virgins.
Bro 1: "Dude I just fucked three virgins"
Bro 2: "Was it in a year?"
Bro 1: "Hell Fucking Yeah"
Bro 3: "I bestow upon you the Virgin Crown"
