stealing the thunder

This idiom is used when a male gets a boner from something sexy and his heterosexual friend gets a boner as well. This is because the second guy reacts with a boner because upon seeing the first guy's boner he thinks to himself, "man, he's got a boner, there must be something hot around!" It is often awkward, especially among junior high and high school kids.

Man, that chick is hot!
Yeah, man. Aw, that's gross.
What?
You're stealing the thunder!
