Funny foreign language (or obscure English) insults

[Reverend Conehead]

My funny foreign insult comes from Swiss-German. It's "Spinchäeb." There's no standardized spelling in Swiss-German, but that's how I would spell it. They say "spin" for the same literal meaning we do, but if someone spins it's a figurative way of saying their crazy. "Chäeb" is a dead horse, so Spinchäeb translates to literally "a lunatic who smells like a dead horse." The use to to call someone a dufus or a disgusting idiot. It's pronounced like shpin-kabe with the K pronounced like you're clearing out your throat. Your turn. Know any foreign language or obscure English insults?
