A condition guys get when having sex, or sometimes just when they have a boner. The girl may get too rough, or the guy sits down the wrong way while having a boner. This causes the dick to bend the wrong way, which hurts like hell and almost makes one thing that it snapped right off.
1) "These jeans are too tight, so that when I pop a boner, I can't sit down without severe fuck trauma."

2) "Watch out for that girl, she plays a bit rough. If you sleep with her, not only will you get herpes, but a bad case of fuck trauma."
