A person who gets their kicks from sniffing someone else's door. Usually the door smeller has an attraction to the other person. Comparable to someone who sniffs panties, but not as severe nor kinky.
My sister's best friend pretends to go to the bathroom and actually sniffs by door when I am away at work. "You're a freakin stalker and door smeller! get away from me you freak!"
