The sack that holds your "nards"... a "scrotum" (abbr. "scrote"), or "ballbag" ("baw'bag" in scotland). Also known as the "wee guys' hammock" since it is the resting place of the little baby machine spermees.
'Watch it, or I'll boot you in the nardsack so hard it'll bust, and you're wee guys will spill freely onto the floor"
Pronounced 'Afden', this is a necessary 'workplace friendly' acronym for the term 'ass-faced-dick-nose'. This acronym also bears punerific humour in it's similarity in sound to 'Afton', which is a region of St Louis highly populated by immigrant Bosnians, most of which have faces that look like an ass, neatly adorned with a dick-like nose. The acronym was created in response to an increasingly 'professional' work environment, in which the term 'ass-faced-dick-nose' seemed to become 'unpopular' with the higher ups.
'Hey, that person is a complete afdn. I wonder if she's Bosnian?"
