mailbox

One of the many ways that heterosexual male friends show each other their genitals to be funny. Kindof like giving somebody the brain or the batwing, the mailbox is the act of flipping the erect penis upward, exposing the scrotum, thereby "raising the flag."

Yeah, he gave me the mailbox. He raised the flag.
