o sniping 

A derogatory term used in the Tribes game universe to describe the act of sniping on the enemy's side of the map.

While often thought to be illegal, this notion has no basis; o-sniping is perfectly legal and often a powerful tactic that the enemy will have difficulty countering because they spend too much time whining about it.

"He accused me of o sniping, so the next time we got into a disc-duel I just popped him in the face with my laser rifle from like 40 feet away, and asked him if that was o-sniping too. Then he kicked me cuz he was a douche."

o sniping 

Offensive sniping. In Tribes, and probably other games, where players with no skill snipe enemies at their own base. This often leads to turtling of the flagholder.
