porcelain welding

Particularly violent discharge of near liquid feces into the toilet bowl, resulting in a splattering effect around the rear of said bowl. Flushing will not remove this weld splatter, and it becomes dried on and very difficult to clean later. Sometimes under extreme porcelain welding conditions the tank, or wall behind may be hit by the weld splatter.

"Man Steve did some porcelain welding after dinner, Who's gonna clean that up"

Spot-Welding 

An act of farting designed to punish the recipient, delivered by two+ individuals. The victim is tackled and held submissive, while the farter drops bare-ass on the exposed skin of the victim. Ideally, the fart is both hot and wet, simulating a "spot-weld."

After Josh passed out from over-drinking, I pounced on him and delivered some epic spot-welding on his forehead that woke him up.
