Rapa tu madre

It’s Dominican slang that implies that you fuck your own mother, that’s to mean that you’re such a dirty, nasty and disgusting person that you’re even able to do that.

Although most of the times, when said to other people, it’s taken as a offensive, it’s common hear Dominicans say it as an interjection.

Qué rapa tu madre tú ere, loco! Cómo tú te vas a comer la comida mía? (What a rapa tu madre you are, bro! How dare you to eat my food?)
