I know this isn’t an always thing, but sometimes when people use this word it sounds condescending.

Person 1: “Oh, so  ___ ___ ___ ___?”

Person 2: “Exactly.”

Person 2 (translated): “Wow, normally you aren’t as bright as me, but when you responded in that way, for one brief shining moment you approached my level of intelligence.”

We’re on to you, smarmy “exactly” users!
