A Scottish term with two related uses. As a verb, to nyaff is to yap or chatter annoyingly — the verbal equivalent of a small dog that won't shut up. As a noun, a nyaff is a small, insignificant, or thoroughly irritating person. The word perfectly captures a specific Scottish disdain for petty, mouthy nuisances. Think of the colleague who talks constantly in meetings but never says anything useful — that's your classic nyaff.
