Although the main definition would be something along the lines of "female incel", the term femcel is often just used to describe various personality traits. Yes, a femcel is a celibate woman (voluntarily or not), but with time, the word has mostly been used to describe single women interested in (non exhaustive list) :
- the internet. Femcels are known to be
chronically online first and foremost.
- being mentally ill, in one way or another.
- being obsessed with femboys/being a yandere.
- listening to "femcel music" : mitski, fleetwood mac, blondie, princess chelsea, deftones, deathgrips...
- having "femcel hobbies" : video games, horror, a mix of both, "cutesy" things, art, spending all day in bed doing
absolutely nothing, anime...
- generally being a social reject, especially in real life, and mostly having online friend (if any IRL friends at all).
"i haven't left my room in a week and my back really hurts."
"Yeah, maybe that's because you've been doing nothing but rewatching
Serial Experiments Lain for the 100th time and listening to three hours deep dives about every PS2
psychological horror games with a woman protagonist you could find."
"lol
yeah i guess."
"You're such a fucking femcel."
