When you start to get a half boner but you start to think of something to take your mind off of it like your grandmother naked so it doesn't reach full maturity of an erection
Bro i did a bonerabortion in math class when i saw Brianna's tight ass in those shorts.

Caleb knew the only thing to do after he didnt get prefect was take a failure shower.
