from http://en.wikipedia.org/wiki/Internet_troll

a troll is someone who comes into an established community such as an online discussion forum, and posts inflammatory, rude or offensive messages designed intentionally to annoy and antagonize the existing members or disrupt the flow of discussion

so lets see...

someone - check you're someone, I'm sure you're not no one.

established community - Rosity is pretty well established check

inflammatory, rude or offensive messages - well maybe not offensive, but inflammatory, rude - seems to fit the bill.

annoy and antagonize the existing members or disrupt the flow of discussion - ahh huh, so what part did I get wrong again?

besides it was a funny comment, ohh come on admit it, I see a smile peeking through... :D

lets laugh with each other not fight.
