A sidewinder is when you put a dip into the side of your mouth, preferably near the molars. The reason for this is that your gums in the middle have been eaten up so badly by years of dipsky abuse that a dip can no longer reside there.

A particular technique for baiting your line when fishing where the hook is indiscriminantly placed in the middle of a long piece of bait. Ensures that bait travels through water in a peculiar and non baitfish manner. Makes catching fish more difficult but you do earn more man points.
Hey JVo, did you catch that fish with a Sidewinder? You must be a superlative fisherman

Also:

To pump vigorously into a receiver who lays on his or her side with the knees brought up close to the chest.
This resembles a baseball bat being thrusted in and out between stacked mattresses.
