The term grundle luber doesn't necessarily have to refer to a person who actually lubricates the grundle; it can be used to refer to someone who is an all around d-bag. Also a good drug smuggling alias.
Tommy loves a greasy grundle cause he's a grundle luber.
Quit being a grundle luber and chip in.
Yeah man, send the pills addressed to Grundle Luber.

When a guy is having anal relations with a girl and pulls out of her bumbum and has poo on his dick, then flips the chick over and uses the poo as lube for vaginal intercourse.
Every girl loves it, a lot.

"Hey man, did you earn your poo dick last night?"
"Yeah dude, and I was a Poop Luber too."
This might be the nastiest fucking thing I ever wrote....

Get the luber than ubermug. This word is derived from the great Bhagat Singh, and is pretty much similar to the definition of Rizz (created by YouTuber and Streamer Kai Cenat), which means to have game with females. There can be many different types of Luber, such as Unspoken Luber, or Internet Luber.
