Describes the unsually close, akwardly affectionate relationship shared by three heterosexual males. No one in the bro triangle is gay but outside observers are often left confused by the considerable amount of provocative, homoerotic humor. Ass slaps, nut taps, and suggestive body language are not uncommon. Do not call them gay or they will not hestitate to train fuck you in the mouth to show you just how ungay they are!

R: "I bet J has a big dick"
G: "Maybe but it's probably a grower not a shower"
J: (pulls pants down) "I don't know man, whata u think?"
