Get the She speaks French mug.
Used for someone (essentially females) who’s fluent at sarcasm/ very good at being sarcastic/ a sharp-witted woman
A: Are you having fun at this party?
B: Oh yes I’m loving it, it’s the best day of my life, being sidelined by my very date, standing here all alone, best day ever!
