Imo, it's better to insult people by using words they don't know that are still in their native tongue. I learned/did that since at least 1st grade/age 6. Called some boys who made fun of *not me* "bipedal pedestrians". Class rules were: no name calling, no insulting, no swear words. Followed the rules totally, and pissed them off intentionally.

Btw, i know like 7+ languages, including fluent dutch (super out of practice verbally in it so id sound like a drunk/normal german or worse).
