Scoping is a online game term or leet speak, mainly used in First-PersonShooter games for killing someone with a rifle gun.
Scoping also is a sexual reference against someone. It's the new "Oi dude, CHECK that bitch out" (Replace check with Scope).
Use for when someone sees someone "attractive" in the distance and says sexist comments towards the person.
"Oi dude, ooh shit, scope that chick out down there!"
"Fuck yeah dude. oh shit, here she comes, don't say anything"
*Person walks past*
"DUDE WAS THAT A MAN?"
"WE WILL NEVER SPEAK OF THIS EVER. STFU"
