People use it interchangeably with the word virgin now. Virgin shaming men is extremely common, now they just changed the word to incel. And tbh why they wouldn't, they mean the same thing.
Of course only retards on inceltears think that to be labeled an incel you have to self-identify as one. Nope. Women will just throw that word out and label men with it. They hate virgins and incels, so of course they use it as a means to shame men.
