I used to do the same thing in PVP. If I was pissed, I'd run threw a low level place, see a group of 20-30s and just start killing. If not I'd just run up to them, wave, and throw down my party keg. Had a 70 run up to me after not killing a level 30, which was rather nice timing on my part since the 70 just waved and ran off.
