slice the Limburger 

To pass gas that is extremely odiferous, super-loud/drawn-out, and/or copiously voluminous, so that said whizzpopper is noticeably more offensive than simply "cutting the cheese".

I chowed down on three bowls of fragrant steaming baked beans at the neighbors' backyard barbeque last evening, and now my butt-hole is parched and raw from having to slice the Limburger all night.

sliver of the moon 

A strange, random phrase used to describe anything. Usually used as an excuse for something you weren't supposed to do. The conversation including this phrase, used by my 3 year old cousin, is shown below.

"Uncle Ben, I don't potty talk. It's just a sliver of the moon."

slice on the mat 

A slice on the mat is a Second War British term. It signifies the eager anticipation of a serviceman returning home on leave; as his woman opens the door they can't even wait to get to the bedroom, and have sex there and then, on the mat, just inside the door. It is still used.

I hadn't seen her for three months, and when I turned up she immediately gave me a slice on the mat. She did remember to close the door, though. . .

Slice on the Side 

A lover other than one's partner.

You break up with your woman? Who is this girl you are with?

We didn't break up. She's just my slice on the side
