Big huge piles of poopsy doopsey normally occuring after ingesting a hash brown or more commonly tater tots from iHop. The tater mud is a mean sloppy poopsy that leaks out of your rectum during poopsy squirts (see sharting).
Guy 1 - I just ate ihop, and I can already feel the tatermud slipping out of bung hole. Can I use your bathroom?
When you and a sibling get into a tater tot war. Multiple tots are thrown at eachother and result in numerous stains throughout the house. Typically tater smudges on windows that dry and become stain-like.
Me: Dude me and my bro got into a tot fight last night.
Other Bro: damn dude, there must've been a lot of tater stains.
