fatcrack 

Technically any fold of fat of a morbidly obese person, but in common usage one that harbors foul-smelling excretions. These can be simple body odor, areas that were too hard to reach during showering, or areas that have become fouled through elimination, the impossibility of spreading the cheeks, or constrained by the shape of a toilet seat (the latter two causing a "muddy fatcrack"). The word can also be used to describe odors caused by a fatcrack - in this case 'fatcrack' is most often experienced when the fat person moves, releasing a bolus of odor, or 'fatcrack'.

1. "Damn, that lady on the bus had some serious fatcrack going on."

2. "What's that smell? - Oh, that's Ruth, she's got a muddy fatcrack".

fartcracker 

When you let out a fart and it hurts your butthole and sounds like a firecracker.

“Technical Term” - When the resonance of a fart creates excessive vibration of the rectum, creating pain.

Doctor to patient - That pain you experienced is what we call in the medical field a “fartcracker”
