The deliberate act of matching speed with a car or truck beside you on the freeway, thereby preventing the d-bag behind you from proceeding with his 90 mph freeway surfing ways.

Also the same general premise of freeway tag, just without the presence of people you actually like.

2. "Ah, flashed your brights.. that's gonna cost you another 30 seconds of sand-bagging, my friend.."
