I have introduced my wife to whole subcultures she was unaware of prior to our meeting. This leads to hilarity when she then has to explain some of her husband’s foibles. Example:

Coworker: This good coffee. Where did you find it?

The Wife: Derek dragged me through the 5.11 store. (Editor’s Note: The coffee is Black Rifle Coffee)

Coworker: What’s a 5.11 store?

The Wife: It’s kind of like a tactical TJ Maxx.
