Kiting in RPGs is a process of keeping a monster (mob) at a distance so they can't do damage to you while you (the character) damage it. In WoW the character classes most able to do this are: Hunters, Warlocks, Mages, Priests and Shaman. (Paladins can do it to Undead, Rogues don't they use stun-lock, Warriors don't have anything for distance.)
Hunters use freezing and frost traps to keep anything at bay, scare beast to kite beasts.
Warlocks use fear on any mobs.
Priests use psychic scream on mobs.
Mages use a modified version; frost bolt slows the mob and if some special abilities proc, freeze a target before it ever gets to them, giving the mage time to damage it or teleport away.
Shaman can drop a totem that slows the mob down and they can attack from a distance or run as needed.
