what do all those Internet Abbreviations mean please?

[TravisBickle]

I have been going on the internet for a few months now... but I have not seen any site explaining the abbreviations.
I am particularly interested in the terms "Troll" and "Nef".

I would have thought you'd get asked about this all the time, but it didn't come up in a search, so there your go...

Troll is someone who likes to just post useless crap on a message board just for attention, just being a pain in the ass.

Nef is an AnandTech Forums creation, synonymous with Troll. However, Nef can be used as a noun or verb (neffing.)
