Something very appealing to lurks, these often result in massive fapattacks after a cluster blubbing sesh. A lurktastic may be anything from a female that they would like to lurk on, or a male that they would like to be friends with, but end up lurking anyway.
Beau found Matt and Andy lurktastic but as a result they became scared when he asked them to go cluster blubbing with him and Michael, and when they refused, Beau had a massive fapattack.
