hair bumming
You stick fake hair on your butt and walk around begging people to scratch it like it’s your job
My cousin glued a whole wig to his butt and asked my mom to comb it. She said no.
I saw a guy at the mall with hair on his butt and he kept asking kids to brush it. He was ridiculous.
My friend tried to hair bum at school and got in trouble for scratching the chair.
