mantry

When your husband/teenage son/full grown male coworker of legal age fixes/cleans/completes something after which the condition of said thing needing fixed/cleaned/completed looks relatively the same as before they "took care of it". That's mantrying.

Wife: Honey, I thought you were going to fold the clothes while I was away this week . . . . (stares at pile of garments)

Husband: (remote in hand) I did (smiles proudly)

Wife: (sighs audibly) Oh. It was a mantry. Thank you.
