A girl who is not exactly fat and not exactly skinny, but definitely attractive. Think "curvy." If she gained weight, she would be "fat," but she isn't yet. She's right on the border. Sex with her will widen (pun intended) one's tolerance range for weight, making heavier girls seem attractive as well. Eventually, the guy who sleeps with the gateway fatty becomes a full-on chubby chaser.
Rick: Dude, Amanda's hot.
Steve: Stay away from her! She's a gateway fatty!
Rick: But she's hot!
Steve: Yes, she is! And if you sleep with her, next thing you know you'll be sleeping with girls twice her size!

It's a fatso and very very ugly to the point where no guys would like it. It sucks at everything it does and calls itself smart even though it cheats off people.

A swell dude named Ty who has a heck of a time getting his life together and as a result just kinda flops fetchingly through life like a lifeless blob of lard swirling in a chasm that is juxtaposed between chaos and helplessness.
