2. A cunning reference to seemingly innocuous yet ultimately crude phrases, e.g.., rusty trombone, most often in conjunction with an apparent double entendre, often in mocking, tongue-in-cheek protest to the brackishness of the former.

1. Lots of golfers use a rusty sand wedge to increase spin and block glare.

2. I spent my afternoon slapping balls with a rusty sand wedge.
