Body Language Through Internet Messaging

What does it mean when a guy threatens violence all the time? Enter into evidence, Exhibit #1 - an IM conv between an acquaintance (hereafter referred to as GoatBonker to protect his identity) and Yours Truly:

[15:22] goatbonker: >:D<
[15:28] darkthalia: :D
[15:28] darkthalia: is that a hug? awwwww ...
[15:30] goatbonker: bear hug
[15:30] goatbonker: *grab ur ass*
[15:31] darkthalia: LMAO *slaps ur hand away and knees u in the family jewels*
[15:32] goatbonker: punch u in face
[15:33] darkthalia: *evade ur clumsy punch and counters with the Fist of the Constipated Tiger*
[15:40] goatbonker: do a crouching tiger and u mis
[15:40] goatbonker: pinch ur nips in return

Is it my fault? He grabbed my ass first. Of COURSE I've got to knee him in the nuts lah.

Is it freaky that a simple IM conversation can get so strangely real?

Aarrrgg. Now I've got more to think about that just a guy threatening to pinch my nips, whatever that means...
