fart roll up 

A fart that instead traveling out to the side or rear of the buttocks, travels forward rolling up past the balls and taint area. It offers a straight-to-the-face delivery making the smell worse than usual.

Diby fired such a mean fart roll up while driving back from Buffalo Wild Wings that he needed to open the windows and decline his seat to avoid getting his eyes burned.

Break Up Fart 

The fart that is the grounds for ending a relationship.

May be loud, silent, smelly, in public or in private.

Gerald: *pfffftt!*
Marcy: "I swear if you fart one more time then it's over. It will be the break up fart"

Marcy: "That's it I'm outta here!"
Gerald: "please baby I'm sorry take me back!"
