How i feel when the enemy jungler takes my buff from me...
i will make them rue this day.
i will make them rue this day.
My favorite is when I find them stealing my buff, and they are at 50% health.

"You will regret your actions... In 30 minutes when I'm done with this item, and this item, and that item..."
Me whenever I see a Shaco Jungle against me, I make it my goal to make him suffer
Time to eat their entire jungle
if they leave one of those small jungle minons there, i just end up leaving it like that and gank hard core. They just eventually counter jungle themselves.
Unless they are Trundle and you decide to not fuck with that guy and camp a lane hardcore.
Welp I was only going to take one of your camps now I will claim you whole jungle, your life, and the life of the laner that came to try and help you after your death.
Kindred every time they steal a Mark :P
I remember stealing the enemy Nocturne's blue buff with Soraka by just last hitting it over the wall and running away. He was quite angry and chased me all the way back to my base, if he hasn't caught up to me I was probably dooming myself to being camped for the rest of the game.
Good luck
