The act of having your nipples protrude out of your shirt, as if to be actually hiding skittles candies underneath your shirt.

If you are smuggling skittles, you most definitely have nip rocks.
1. Dude, you ever watch the Friends episodes where Jennifer Aniston looks like she's smuggling skittles?

2. That shirt is so tight, you look like you're smuggling skittles.

3. Don't wear a bra...guys love girls who look like they're smuggling skittles.
