Get the Mellow Yellow mug.
Giving someone a mellow yellow is when you act like you are going to bust a nut on their face, but instead you let forth a flood of urine all over them.
Best used when you have someone that brags about how good they are at giving head.

Mellow Yellow:

A Redneck, "I drank some meller yeller today."
Not a Redneck, "Why would you drink that Satan's piss?"
A Redneck, "Trump told me to."
