bro-jan horse

when a bro in an attempt to hook up with a drunk chick and does not have a condom shows her the empty condom box and says that he has one and continues to have un-protected sex

Bro 1: "Dude how was last night?"
Bro 2: "Didn't have a condom"
Bro 1: "So nothing happened?"
Bro 2: "You kidding? I gave her the old bro-jan horse"
