Lol. Redditors throw around "incel" the same way that 14 year old boys threw around words like "gay" back in the early 2000s. It's a label that elicits an "ick" factor and makes people feel the need to distance themselves from it. But ultimately it's a flippant pejorative that comes from a place of insecurity and a desire to fit into what's perceived as socially correct.
