(noun) 1. An insult - Usually a female who is thought of as someone who sluts-around. 2. An expansion of the insult "trailer trash" taking the term to a level that encompasses the type of trailer trash who sucks dick a lot (A LOT!) and swallows so much cum that her belly is full of it, causing her to "burp" or "belch," if you will, cum.
I wouldn't take Jane to any kind of fancy resteraunt since she's nothing but cum belching trailer trash anyway.
Why would you want to meet chicks at the flea-market? All you're gonna find there is a bunch of cum belching trailer trash.
Benching is when you start dating someone you think is nice and who has potential, but you're not crazy about them. You don't know wether to keep dating them, or dump them and move on to the next one. This is where benching happens; instead of going for either of the above polarized options, you put your date in your mental 'maybe' folder and 'bench them' so you date around to see what else is out there.
Sarah: How's your dating life going, Jill, weren't you seeing that guy Jack?
Jill: Yeah I am, sort of. He's just ok, so I've been benching him and dating around more.
John: Hey Jack, how are things going with that girl Jill you're dating?
Jack: Idk man, I know she's seeing other guys, and I think I've been benched.
