A person who aggressively pursues physical contact with his or her mean, cranky, non-cuddly friends. Cuddle sluts can sometimes be as persistent as telemarketers.
Telemarketer: Would you like to buy a new credit card??!
Me: I'm not interested. (I hang up)
Cuddle slut: Awww, you look sad!
Me: No I don---
Cuddle slut: Awww, I think someone needs a hug!!
Me: I'm not interested. (I leave as quickly as possible)
