I have the kind of super long and thick hair that gets attention. Most of the compliments I like. I did after all use a lot of effort and time growing and taking care of it.
Once, at work, I got approached by a guy with a fetish for long, reddish hair. He proceeded to tell me how great of a boyfriend he'd be, how he'd wash and brush and take such good care of my hair. I was disgusted. And that disgust got associated with my hair. It took a couple of days for that disgust to fade and during it I did not like my hair.
If that kind of shit happened often I'd totally see myself cutting the hair off.
This. In general it refers to social awkwardness related to autism. Heard it used mostly as a slur/insult where I live.
