My bitchboy is so cute now- he's become a total salon slut!
adj. Mentally cleansed, espeically of behaviours, attitudes, or even memories considered "undesirable" by one partner.

GF2: "He doesn't even recognize his old girlfriends anymore..."
GF1: "She took him from free-range boi to shampooed toy!"
