Nutgasm 

To bust a nut in a orgasmic way

Not to be confused with an orgasm though; that's hella gay

"That new car smell makes me nutgasm."

"Nah, it's all about that new book smell. That's worth a good nutgasm."

nutgas 

The sensation some males experience when farting while seated. When the gas has nowhere to escape, it often gives the feeling of a bubble swelling around the scrotum, or nutsack.

"After eating that burrito and having to sit in my car for an hour, I had mad nutgas."
