# That's Groovy Tee

A black tee with the joke running the other way: Grandpa says "That's groovy." and the teen wonders about an app. For grandparents who still say groovy.

## The Joke

The shirt prints GRANDPA: "That's groovy." and GEN Z: "is that an app". "Groovy" is 1960s and 70s slang for great. The teen has never heard it said out loud and guesses it must be something downloadable.

## Design

The front shows two text-message bubbles with thick outlines and offset shadows, printed large on the chest. The GRANDPA bubble is yellow, the GEN Z bubble is cyan, and the caption LOST IN TRANSLATION runs underneath. A small genzdecoded.com line sits below it, and the little two-bubble GenZ Decoded logo is on the left sleeve.

## Made For

Grandparents who still say groovy and the grandkids who never have. It lands best when both of them are wearing one.
