Fanboy

The fanboy, unlike the common fangirl, is a more solitary creature. They are not as prone to stampeding, but should still be treated in the same way. Like the fangirl, the fanboy also shows zero maturity or emotional restraint, often by being patronizing to other fans and being amazingly perverted towards their lust object.

A fanboy will often learn every aspect of whatever he is a fan of to the most minute details, and disdain of anything that is not what he is a fan of.

Fanboys tend to be part of flame wars.
