there was a young mouse called keith,
who bit a mans knob with his teeth,
it wasnt for leisure,
or sexual pleasure,
but to get to the cheese beneath

(also bell end brie, helmetdale)
the smelly dirty shit found under the foreskin of tramps and other scum

the dirty yellow cheese under ones foreskin

What? No VIZ readers posting to this site?
Knobcheese = smegma
If you don't know what that is, visit a REAL dictionary, you bell-end fuckwit.

Way of calling someone a prick, or an asshole. Refers to the stuff under a guys foreskin

The actual name is 'smegma' found behind the foreskin, it usually smells and is fairly stringy and usually yellow in colour

1: This 'cheese' stuff that's under your knob if you're a lazy prick and don't shower

2: Derogatory, used when someone is being a dumbass or just to put someone down.
