A hardcore variation of the game Jenga where you aren't allowed to use your hands to touch the blocks, nor can you use your hands to manipulate other things to touch the blocks. Typically the penis is used to push the blocks out, but you could also use your mouth/tongue as well(not advised).
Me and the boys were playing Boner Jenga all night yesterday.
A term meant to be used with the movie "The Avengers", a costume boner refers to any point in the movie where Loki's long-horned helmet and cape suddenly appear. This usually happens when he is exerting some type of power, such as when he instructs an entire crowd of people to bow to him and they obey. Much like a penis might become erect when the average male gets excited, Loki's costume tends to appear in similar events.
Hey look, Loki's kicking some ass! Oh look, another costume boner.
