Had a pretentious friend correct me on the pronounciation of Ibiza and Barcelona, stating the locals say it the way he said it. I held my tongue, and steered the conversation to other things.

He mentioned Germany, and with the arrogance and smarm of a thousand reddit liberals, I hit him with, "Actually, the locals pronounce it as: DOOOOYtchLANnnn." Saying it as obnoxiously and with as much spit and I could fling.
