The disease-like condition when you start gaining romantic feelings for a tease (typically women) who openly flirts with everyone for his/her own personal benefit (AKA, an attention whore). S Tease D's can be very serious and can last for days or even years. There is no cure for an S Tease D but there are treatments. Treatments include strip club patronizing, booty calls, introductions and conversations with new prospecting individuals, and social avoidance of the infecting party.
I don't know why anybody would want to go out with her. She only gives guys S tease D's.
