Someone who thinks almost exclusively with their dick (or vagina) and goes on and on about porn and anime tiddies to the point of being annoying. Might also be an incel. Should probably have sex and stop watching so much porn so they can stop obsessing over it. Will likely argue that being interested in sex is natural or some bullshit, ignoring the fact that fapping 5 times a day isn't normal at all.
