F'nice

Adjective, pronounced 'fuh-nice'.

This portmanteau is used to describe a person who is thought to be good looking and would normally be described as 'fit', however, there is someone else in earshot who would take personal offence (boyfriend or parent) and therefore 'nice' is quickly inserted as a substitute.

Ben: Yooo, that girl over there is f'...
*Nathan (girl's boyfriend comes over)*
Ben (continued): f'nice. Hey, s'up Nathan!
