Slappy Fart 

A flatulent so powerful and instense that it vibrates your butt cheeks so hard and causes them to slap together profusely!

Cortney had a case of the slappy farts I knew because i could hear them from across the room!
Kelsey woke up and felt her butt cheeks vibrating and just knew she had the slappy farts!

When sitting in class and you try to ease a fart out silently, but its very loud and leave debree in your trousers and on the floor.

Dude, I was sitting in class talking to a hot chick and I blasted off a sloppy fart

Sloppy Joe Fart 

Little bit of poop that shoots out and gets stuck in the butt crack. Causing Sloppy Joe Buns.

The buffet last night gave me Sloppy Joe Farts.

Sloppy Joe Farts are the leading cause of SJB

Sloppy Jalopy Fartcake 

When you stretch a woman's bunghole pretty wide, and take a shit in her ass, and fill it up with all sorts of magical drinks, beverages and other fizzy stuff. You then jam a buttplug in her asshole for 30 minutes, the whole time she is running around a racetrack full of crippled deer in order to make the concoction rather fizzy.

She will then release the plug this, causing a rather large farting sound due to the built up gas, and a nice mess on the floor. Proceed to pick up this mess with a flask, and pour it into her mouth while farting down her nostrils. This will cause her to suffocate and regurgitate the delightful product that you have made in order to feed to your cat, who will enjoy it thoroughly, or your money back.

L: Dude I feel like a Sloppy Jalopy Fartcake with my bitch tonight.
C: Sounds delightful.
