You may have noticed your pants getting a little snug during the holiday season. That could mean they’re just extra comfortable or it could be another way of saying they're feeling a little tight.
Snug describes something that's comfortable and cozy. During a snowstorm you may take shelter in your snug cottage in front of the fireplace. When talking about clothing, snug means fitting tightly. Clothing may be snug on purpose, like a bathing suit, or it may be snug because it’s in fact too small. If you’re “snug as a bug in a rug,” you’re as cozy as can be, or metaphorically speaking, in a very comfortable position in life.
