Derived from Gutterslut, a gutter is quite literally a repository for liquid waste. A true gutter is a casual whore, no major daddy-issues or insecurities, simply an effortless lay. In the colloquial sense, a gutter is defined by a girl about 15 pounds overweight with a questionably cute face who will go home with you at the snap of a finger. Usually a dead-fish in the sack, gutters are good for one thing and one thing only: providing a moist orifice for which men can drunkenly pump loads into until they pass out.
Redneck 1: Man, that gutter from Tuscaloosa gave me the clap last weekend.
Redneck 2: Damn straight son, I told you not to mess with that slut. She gets passed around like a joint at a Willie Nelson concert.
"So, I was eating my burrito and I decided I wasn't hungry anymore so I threw it in the trash. A couple hours later I decided I was still hungry and knew I put a burrito in the trash. I then picked it up out of the trash and ate it."
"Dude, that's gutter."
or
"I'm so horny I'm swamping" "Ew Laura, that's gutter."
