A nickname given to someone whose brain has seemingly turned to mush after smoking too much marijuana (or actually using too much of any drug but primarily used in association with pot heads)
Tommy: Yo, Nicky has been saying some really weird stuff as of late.
Brian: so you've noticed that too huh? I think we're gonna have to start calling him "Mush" now.
Tommy: I kinda figured that would eventually happen with him but I didn't think it would be this soon.

Get the mush-eatingmug. Mush is an entity in itself. A special sight, massive in stature. He lies in the mid-range between a Big Chonker and Oh Lawd He’s Coming. He appears lazy and grumpy at first glance, but that is a rare, ancient, apparatus utilized to conserve energy for the betterment of society. He is graceful in his nature and has a multitude of specialized skills. You won’t be mistaken when you see Mush. Always greet him with the utmost respect and gratitude.
“Hey look over there! That has to be Mush!”
“The end of WW2 began upon the Mush great head-butt which landed in the locations of Hiroshima and Nagasaki.”
“Woah, that’s a good ole’ lad, hey Mush’”
