Johnny: Did you hear about when n0valyfe and zezima clashed for the #1 ranking on LOLrunescape, isochronously?
decent kid: uhh...no.

Johnny: u a noob!
decent kid: the only good part of this conversation was the fact that you used the word "isochronously."
Johnny: u didn't responz to my insult!

decent kid proceeds to shoot Johnny in his cerebellum and give him a good kick in the nuts in an isochronous manner.
