nobsack

Literally - The bag of balls thats hangs beneath the penis/cock/dick/nob as part of the male genitalia.

Metaphorically - Someone who you really dislike and want to insult. It usually just comes out as you cannot think of a better insult.

"Jonathan i dislike you"

"Yeah well i think your a complete ... nobsack"
