nuftumble

If you can't describe something just say nuftble it will always be there for you but it is up to the person your talking to to put it in context

Man 1: dude last night was so... I forget the word... oh well. NUFTUMBLE

Man 2: well because your saying in an excited voice I assume it was really fun and kind of scary

Nutrumbler 

When your sitting down and your balls are a tad sweaty and you fart and the fart causes your nuts to rumble.

I was in the middle of a gaming session and i pulled a nutrumbler.
