Melting roommate

A person who takes off all their clothing and accessories when he or she gets home from work or from a night out and leaves them exactly where they took them off, creating a puddle of articles, giving the impression that a person melted there. A source of irritation and contempt for the more organized roommate.

P1: "I thought my roommate died or was abducted by aliens, but it turns out I just have a melting roommate."
P2: "You're out of salsa."
