Two roots for 'fart' are usually reconstructed for PIE: *pezd- and *perd-. We get English partridge from the latter. In the Rhineland, I once introduced to Nonnenfürzchen which looked a lot like donut holes to me. A friend ordered them, and told me what they were called after we left the bakery. The joke was on me when I went back alone to order some, but didn't know their polite name. I pointed and asked for some of those.

Ceci n'est pas un seing.
