well, since runvardh feels welcome to post in the NT threads, I'll make myself at home posting here
(yeah... it's not nice to discriminate against different types!)
The warning of "you've minorly annoyed me" is receiving the "I will cut you" look... and maybe a snarky comment or two.
It actually takes quite a bit to make me genuinely angry though, mostly because I'm lazy and don't care to invest the energy in anger unless the person is without a doubt deserving. Then I find something they value and destroy it... this gives me endless satisfaction!
(like selling thier camera to a pawn shop, or proving to them that thier SO loves someone else
)
I usually wait for a couple of weeks for revenge though, so that it's even harder to trace back to me
