To invent a nonsensical saying and convince an ESL student that it belongs to standard English idiom.

Kristen: That just slaps my goat!

André: What hell? What does it mean?

Kristen: Oh, that's just a common saying people use when they're upset. It's like "grinds my gears", but more backcountry.

André: Ahhh. I see.

(André just got goatslapped!)
