Bald Fetish
The fetish to want to have sex with a bald person's head, pour hot butter on it and lick it off, put an XXL condom on a bald person's head and shove it up someone's vagina or asshole, effectively suffocating and killing the bald person, etc. Bald fetish can also tie with the fetish of finding shaved ball sacks insanely attractive.
"Yo Andy, that guy's looking at your naked head really weird. I think he has a bald fetish."
At that, Andy ran.
