Oh this is a simple one.
Kiting is basically being offensive from a safe distance.
That's why people fear Caitlyn
in lane, her auto-attack range and W range is so high range and power scares most ADCs who don't have a tanky support.
In the mid or late-game some refer to orb-walking as kiting.
Orb walking is a constant switch from moving to basic-attacking back and forth.
Not like Kalista's hop, but more like a
Lux who Q -> Auto-attack -> Move -> E -> Auto-attack -> Move.
If you want to start with a few ADCs, try Tristana first and don't fight until you've gotten your ult.
Orb-walk ( Attack -> Move -> Attack ) minions so you don't get hit by their support's abilites.
If you ever master Orb-walking, you can master
Vayne.
But in short, kiting is doing constant damage to an enemy without having to get too close or get close enough for them to attack you.
Like a kite which foreshadows someone's face, you're blocking their light.
