look up any word, like pussy:
 
1.
Boneboxer (n): Having a boner in (his/the) boxers/shorts.

Slang that evolved among me and some friends a few years back, when we were camping, and I woke up in the middle of the night to go pee, not noticing I had a boner in my boxers. Unfortunately some of my friends that were still up noticed.
Dude, I dreamed about the hot girl from yesterday, I woke up with a boneboxer!
