Looser than what?

[RoryN]

Just a small problem that I need feedback on. This sentence:

"The guy's inhibitions were completely shot and his tongue was looser than a spinning dreidel."

He's drunk. I'm well aware that there is something wrong with the imagery here, which is what I need help with. I'm having trouble coming up with ideas to fit in the "looser than ...." phrasing.

 

[RoryN]

Okay. I had an idea. How about,

"..his tongue was looser than something that doesn't quite fit into something else."

?
I'd be fine with that being more humorous than poetic. I just wanted to make sure 1. it makes sense and 2. it's really as funny as I think/thought it was.

Then a bolt that had lost all its threads?

looser than a prom date's bra clasp?

Haha! That's perfect Mr. Master!
