A French Nub
A French nub is a guy who thinks he’s the only one who can eat cheese and baguettes properly, and he’ll give you a hard time if you don’t.
He gave me a hard time for eating my baguette with a fork.
He told me I was a 'cheese traitor' for using cheddar instead of Brie.
He refused to speak to me for a day because I used a sandwich instead of a baguette.
