ass is grass 

An expression foretelling a person's doom or demise. Originated from the fact that a murdered person's body decomposes and then provides fertilizer for grass, hence the "ass" becoming grass.

Your ass is grass if she gave you head while we were dating.

Ass-Rice 

The white fragments of toilet tissue that get tangled in the hair around the anus after a particularly wet bowel movement. Unless removed immediately, ass-rice can cause great discomfort.

"The toilet tissue in the public bathroom is so cheap! Not only does my finger break through it but I have to spend several painful minutes picking out the ass-rice left behind."

John discovered a massive clump of ass lint buried deep in his ass crack, and flung it at Bryan while typing this.
