A nearcel or incelish man, assuming he has an average income, constitutes a "3" on the decile scale. A nearcel is nearly incel and may experience lengthy dry spells or have to lower his standards to an extremely low level to obtain sex. As Mainländer explains, nearcels "aren't kissless virgins or anything but they have WAY less sex and with WAY lower quality girls than what they'd need to find it minimally satisfactory."
A incelish person is someone who fits many of the criterias for being an incel, but isn't quite incel. The average incelish man simply has perpetually long dry spells without relationships or sex. The main difference between the incelish man and incel is that while incels usually feel hopeless, the incelish feel that way to a much lesser extent. Although he is typically hopeless at dating, once in a while an average-looking woman may come along who settles for him, maybe due to being exhausted by the dating process, for pity or some other reason.
The main difference between incelish men and incel men is that whereas the latter may not have even touched a woman before, the former may sometimes reach first base (kissing), or if encountering a female pity fucker, may even get lucky and reach 2nd base (touching through clothes).
The other difference between incels and incelish men is that whereas the former doesn't have any luck with women whatever he does; the latter may eventually manage to land a below-average to mediocre looking woman after engaging in two decades of looksmaxxing, wealthmaxxing etc. and by enacting the betabux role.
