Funny Acronym Mug — "Officially Grumpy" (OG) Coffee Mug

"Officially Grumpy" — say it without saying a word. A funny coffee mug and gift for dad, made for a birthday.

Who it's for: the dad who complains about getting older, the grandpa with a grumpy streak, or yourself — buying it for yourself absolutely counts.

When to give it: Birthday, Father's Day, Christmas — or any day he's in a mood.

Why it works: It lives on the desk, not in a drawer: every coffee refill is a small reminder of who gets their sense of humor.

• Big 15oz glossy white ceramic coffee mug — room for the second pour without the refill trip
• Dishwasher and microwave safe — the joke keeps its shine
• About 4.6" tall, 3.4" across the base
