1. Leaving in a “bomba de humo.”
Doing a “bomba de humo,” or “smoke bomb,” is leaving a party without saying goodbye to anyone. Also known as an Irish Exit, what may be acceptable in the Emerald Isle is a big No-No in Buenos Aires. Vanishing without doing the rounds of kissing everyone farewell, even those you don’t know lurking among your friend group, will leave people thinking you are rude and they will definitely take you up on it the next time they see you. Just suck it up and say “Chau” to anyone and everyone. It’ll keep you on the right side of wrong.
