I hate that fucking word, stop using it it makes you look stupid, conoisseur is not a word in french, connaisseur is a word so using conoisseur as an expression meaning you know wtf youre talking about when the word itself implies you dont know wtf youre talking about makes it ironic and i get a laugh each time but still its annoying as fuck will people ever stop using that fucking word?

So... what other expression really grinds you gear(s)?
