Dirty Boxer 

This action is carried out when you are getting head from a girl you really don't respect. You first blow your load in her mouth because you don't care about her, then when her mouth is off of your shaft you cold cock her right in the jaw, making her resemble a very dirty boxer!

Last night I pulled the dirty boxer on a bar slut, it was magical!

When you succeed putting your unerrected cock into an unconsented hobo's asshole and then you get an erection inside him.

Eric: Dude, I gave a Dirty Boner to a hobo last night.

Guillaume: Did you wash your cock?
Eric: No. I like it better with this human nutella on it.
Guillaume: You're so funny. Wanna fuck?
Eric: Awesome dude!

Dirty-Boner 

When you slather your dong in chocolate so that it is lubed better and your spouse agrees to do anal, but when you finish doing it with them, they turn around and turn out to be a guy.

"Oh man, last night was WICKED! I was all ready to go and he pulled a dirty-boner on me!!"
