earlobe fetish
an earlobe fetish is when you get super turned on by certain earlobes and you have to touch them or nibble them.
She came to my house and I had to nibble her earlobe. I couldn't help it.
He bit my earlobe so hard it felt like it was gonna pop off.
I asked her to the dance. She said yes, but only if I let her nibble my earlobe.
