French noun referring to a woman (not necessarily French) who inspires you disgust or scorn.
Can also be used as a mark of affection for friends you enjoy teasing.

Very often, you will realise that a 'radasse' is also a 'grognasse'. But not always.
"Grosse radasse, tu pourrais répondre à mes textos!!"

"Quoi, tu as invité cette vieille radasse de Gabrielle ? Cool ! :)" - use the context to know when radasse is used in a friendly way !
