Maddy is a rat. Trust me. The only thing good about a "Maddy" is that when u put her on a leash she won't run away. Maddy's are rats wothout tails. Maddy's are bots. My maddy that I own has a full enclosure of a 55 gallan tank. She does get fed everyday but it is hard to take of her since she is ugly to look at. That's my maddy. How about urs.
"Hey look its Maddy the rat."

A Mixture of Adderall and Molly. The mixture requires an Adderall 30 mg capsule, a portion of adderall is removed and replaced with Molly or MDMA. Maddy is very enjoyable because it creates a much more potent release of dopa mine.

Usually an Attractive female that comes across as very nice and outgoing, however in reality she is actually just a massive cocktease. A Maddy is actually a women who flirts or touches a man in order to make them feel as though they are actually interested in them when the reality is the exact opposite, they are actually just trying to screw you over or break your heart for their own amusement, Maddy's may come across as nice but they often conduct themselves with the mentality of your typical basic bitch on snapchat or instagram and they are typically found at venues with a large gathering of people such as Night clubs or House parties, usually they'll invite their victim along to make them feel like they're making process only to ditch you after five minutes and go off grinding every second guy in the Venue while completely ignoring you most of the time making you wonder why you even bothered going to do anything with her, do not let yourself get tricked by a Maddy.
Guy 1: Hey man, did you hook up with that girl you were going to Rob's party with?

Guy 2: No, it turned out she was just another fucking Maddy.
