look up any word, like plopping:
 
1.
Someone who is a muppet but also awesome. Very relaxed which can lead to an inability to see things when they are staring them in the face. Incredibly funny and intelligent, usually good at sports and other such things. Can perhaps underestimate their own strength leading to injuries of others. Incredibly attractive but also addicted to things such as nutella and whisky.

The pimple found on the butt of a Gorilla (see Goach )

I once shat a gorillas noach off in 'Nam.

N'oach is a term used to describe a severe lack of roach. Roach is the vital tool when making a doley. When we have no roach, it means it is bad, i.e N'oach.
Stezza: you got any roach?
Rancid: N'oach!
Stezza: oh shit, we got bare N'oach!

Or

Stezza: Sort me some roach.
Rancid: N'oach man.
