When a guy gets really excited, something goes up in his pants; most guys want their penis to be this big all the time
My friend had a boner in science class and asked me to sit on his lap to hide it from his friends. It is usually VERY embarrassing.

A boner can be when a guys wanker starts rising and sticks up like a sword. If you got a tiny cock you will have no issue with someone seeing this but if you got a big daddy then you will get noticed.
