For some reason this word popped into my head and I thought about being "snug as a bug in the rug" or comfortable and warm.
Then there is the action of tightening a bottle cap.
Or snugging the handle of a faucet - to keep it from dripping.
Then there is that pesky reference in books that are set in England - the snug of a pub or bar. What is that?
Can you think of other "snug" references -- off the top of your head?

P.S. To save you some time : I searched for "snug" and only the two "Cup of Joe" thread entries had some interesting references.
