Get the shiznot mug.
Meaning an exact opposite of shiznit with emphasis on the NOT - as reference to movie Wayne's World
Your cooking is the shiznot!

Get the shiznot mug.
The sticky tarry poop that sticks to ur ass after you take a big crap. No matter how hard you wipe your ass more and more crap keeps showing up on the toilet paper.

Hurts alot of if you ate spicy food first.
Man that shiznot was nasty! Now I need to go buy more toilet paper.
