GMS 

Gay Male Syndrome - the phenomenon where straight male or female exhibits behaviors that are normally seen in gay men. For example, offering design advice, desire for multiple sex partners (preferably in police or firefighter uniforms), and obsessing about going to the gym.

My friend Stacy was telling me that she stopped eating, doesn't want children, decided vodka tastes delicious and wants to screw an anonymous 25 year old. I said "Girl, sounds like you have GMS!"

GMS stands for good man syndrome. When a person does something good for you or just in general he is a good man. But when he repeatedly does something for you he has good man syndrome.

That bartender gave me another free shot, he's got GMS.
