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."
