Mr. FatNut 

Is an amazingly kind and loving man, he will never judge you or degrade you, he is always here for you even if he doesn't want to be or have to be he is always there for you to lean on , sure he can be a little distracted but only with important things and never ever will he hurt you or treat you like he hates you. Mr. Fat nut is great when he is laying his pipe and his eyes are hypnotic when he's staring down at you . This man is a dream come true and it's truly a blessing to wake up and smell his non stop farts . You'll never forget this man and if you let him go your surely a fool bcuz you don't know happiness until you are living with Mr fatnut

Oh Mr. FatNut I think I manifested you , your so amazing it's like a dream come true to be beside you!

Fartnuts 

The "Oh,no!" lumps in a fart that you knew in advance that you shouldn't have risked, due to recent diarrhea.

I felt the fartnuts, and knew that I had to go home to change my shorts.

Busting a Mighty Fat Nut 

v. Ejaculating in a satisfying or otherwise noteworthy manner, especially if an unusually high volume of semen was produced. If the nut was busted under embarrassing and/or hilarious circumstances, chances are it was a mighty fat nut.

I was jerking off in my room, and right as I was about to finish my mom called me down for dinner, and I yelled "coming!", then started laughing really hard at the double-entendre, but the laughter made me double over and I ended up busting a mighty fat nut all over my brand-new polo shirt.

Bust a fat nut 

When you masturbstate for straight 6 rounds after an extended period of abstinence due to circumstantial inconveniences.

End of the summer camp:
Jim: ‘Ye when I’m back home imma bust a fat nut’
Jack: ‘nice’
