Bringing the wrong beer or drink to a party.
Julie made a huge Faux Brew Pas when she brought wine coolers to the annual cocktail party. It's a good thing no one respects her in the first place.

I went with my girl to her folks cabin for the weekend. I brought a case of Summit hoping to impress her dad but I realized I made a Faux Brew Pas when I saw him drinking PBR and he thought I was a city-boy hipster.
