So I was playing skirmish in the crucible when I was tea bagged by another player, normally I would let this childish behavior go but I was on a losing streak so this irked me greatly, so I began focusing on this sole player, each time I saw him I make sure to kill him, focusing on him above all else, I'd also throw in some taunts and tea bags so he'd know why I was killing him, eventually he raged quit allowing my team to now decimate the opposition giving us an easy win.
Afterwards In the rewards I got a legendary sniper rifle called "low grade humility", with a description of "I'm good at this" I almost died laughing! Wish I had a video of it.
TL;DR be careful who you tea bag!
