look up any word, like usuratonkachi:
 
1.
The most vile and disgusting thing found on Earth. Often a result of laziness due to a lack of shaking a ketchup bottle before spewage onto a plate of fries or hamburger.
I would rather drink diarrhea vomited from your mother's ass after being fermented in a hippos vagina for 8000 years than ketchup water touch my fries.

2.
the undesirable liquid that collects inside your ketchup bottle if you leave it for a period of time.
dude: wow, these fries look great, but they'll be even better with ketchup!
*squeezes the bottle*
Fuck! Ketchup water!
