Grub you eat when you have mad munchies. Translation: Food one eats after consuming mass quantities of marijuana.
This dank ass bud gave me such hardcore Munchies I had so many Mun-Grubs that I shit like a champ for like 2 hours, I almost had a full blown Fitzgerald afterwards!
Before we Blaze we need to go get some Mun-Grubs so we won't have to move later."
