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.

An amusing road trip past-time.

The intentional, and often hilarious, mischievous brother of the speed limit demon.

Also the same general premise of freeway tag, just without the presence of people you actually like.
1. "You, me, a semi, and the speed limit... Let's all get to know each other, shall we?. Let the sand-bagging begin..."

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

v. (to) Similar to teabagging; done after one has shaved off thier pubic hair, and it has started to grow back. The hair on one's balls is then scratchy to touch, like sandpapper. When you go to slap your balls against anothers forehead it is so sharp that you tare skin.

Sand-bagging people when they are passed out is fun, but tricky.

In gaming, the act of slowly leveling while otherwise increasing stats and currency in order to be stronger than other players at your same level; who have not sandbagged. Particularly useful in pvp focused games that pair players based on level.
