Ocho Cinco
When you bonk your wife in the face with your head after she yells at you for having her inside your car with some other guy's junk.
I bonked my wife in the face with my head after she found a bunch of condoms in my car. Ocho Cinco, baby.
She yelled at me for having her in my car with some dude's junk. So I headbutted her. Ocho Cinco.
After she caught me with another guy's junk in my car, I headbutted her. Ocho Cinco, that's what I call it.
