If it existed unironically on 4chan or whatever before breaking containment I would not have seen that. I can just say that in the first months that it came to my attention, it was always ironic.
I’ve always seen Chad as an incel’s aspirational projection of how to get out of being an incel, as opposed to a true happy himbo, which is not something an incel is capable of understanding. When an incel does bombastic and destructive things in order to get attention, they are channeling Chad to one degree or another. The results are disastrous because Chad is a cartoon character who cannot grow beyond the bounds of the incel’s imagination.
The ironic version of the meme makes me giggle because by reversing the polarity but still insisting that Chad is the way to be, it gets at the absurdity of accepting an incel’s idea of how to not be a virgin anymore, or even of accepting the significance they assign to ‘virginity’.
