Funny Acronym Mug — "I Do Know." (IDK) Coffee Mug

"I Do Know." — say it without saying a word. A funny coffee mug and gift for the friend who speaks fluent acronym.

Who it's for: the expert coworker tired of being doubted, the sharp mom, the friend who's always right, or yourself — buying it for yourself absolutely counts.

When to give it: Birthday, promotion, Mother's Day — or any time someone second-guesses you.

Why it works: Coworkers read it, roommates steal it, and it quietly becomes their favorite coffee cup in the cabinet.
