'Sperg' is both a verb and a noun. It's almost always used for Internet purposes, and to sum up, it pretty much means a person with Aspeger's (or perceived to have it) that gets so dramatically passionate about a subject to the point where it's greatly aggravating to everyone else.
Some people find it offensive, others think it's the perfect term to describe their Asperger's. It'll all a matter of preference.
