The enormous feeling of relief one gets after letting out a huge fart that's been brewing for an extended period of time.
Dude, I was with my date last night and I had massive gas that I was holding in all night long. After she finally left it felt so good to let it go...it was totally orgassmic!

"Oh god I had an amazing orgassm last night."

"Baby, I'll fuck you so hard in the butt, you'll have one hell of an orgassm."
