While U are being a Prick and stealing the Second spawning of blue buff...
At least CLEAR THE WHOLE FRAKING CAMP!
Even if u are deluded that the game is not winnable by teamwork and its you and only you that will ensure victory at least just be a sport and finish the camp so the jungler wont need to wait as much for the next one.
If u ask me stealing a junglers buff and not clearing the whole camp is Griefing : "Assisting enemy team". Its a defining example for "Assisting enemy team"!
This is probably happening more often then noticed; In my example i was engaged in a 3v3 at bot lane including the enemy jungler, when i realized 4 min later that my blue was stolen i first thought it was stolen by the enemy, but after rethinking when could have they taken it and noticing the mid laner had one he was the most probable suspect, I asked and he confirmed it.
It was said 1000 times before , ASK for the buffs!!!
