>>236840Because they're weaboos and they think it's sexy, because weaboos are fucking idiots. They're taught by everyone in their retarded community that ahegao represents a woman at her highest state of arousal and since anime is more easily streamed than ever, weaboos are fucking everywhere. Combine that with neetbux and give it to a girl who would happily eat bird shit off a plate for 200 dollars and there you go.
