Grunds 

A pair of underwear that has been worn for an extended period of time, giving them a crusty appearance and a musty odor.

You better change your underwear soon or they’re going to turn into grunds!

grundel 

Grundel is another word for chad: the region between the balls and the arse-hole; can be an erogenous zone for some.

Girl: I was fingering that part between his balls and his arse and there was shit there.
Everyone listening remained silent but later laughed among themselves:
'Eww! He had a shitty chad.'

When you measure your dick, you don't start at the arse-hole and include the chad; you risk getting shit on your measuring tape.

Q: What on earth is a grundel?
A: You know, the chad, the part between balls and arse.

Grindset 

Being in a state of absolute Grind.
The bag comes first. Everything outside of the bag is a distraction. In order to obtain the bag, one must have a Grindset mentality.

In order to grind, you must be in the grindset mode, otherwise, you're just playing yourself.
