People who show up to parties and don't pay for anything. They steal your beer and liquor without paying. You can spot a slider by hearing phrases such as:
"What kind of beer do you guys have?"
"Dude this party is awesome, can I have a beer?"
(walk in the door) "Next on the table"
(walk in the door) Amy: Hey guys sweet party
Chuck: ...thanks?
Amy: What kind of beer do you guys have? (holds a beer examining it)
Chuck: ...Keystone
Amy: Cool, next on the table!
Dave (to chuck): Sliders...

Get the Sliders mug.
A dirtbag who somehow has scraped enough change together to make it from some crappy Atlantic seaboard state down I-95 to Florida, and then was to laxy to go any farther. Usually, the plan was to go to Miami, but they ended up polluting the streets of Jacksonville Beach. This can be a male or female, young or old, usually of caucasian ethnicity, with limited education, and absolutely no class whatsoever. They are easy to spot by their sideways ball caps, fake gold jewelry, wife beater t-shirt, and always have a cigarette hanging out of the side of the mouth when talking. This creature can usually be found drunk or fighting, when not busy stealing.
Did you see that tool riding that bicycle with the ape hanger handlebars?

Yeah man, what a slider--look, he even has a Salt Life t-shirt! Ha! Go home to Delaware man!

A derrogative term for white castle burgers, for when you eat them you more than likely get the shits

A slider is a large glob of cum that a guy shoots down his cocksucker's throat when he blows his load, instead of spurting several smaller cumshots.
Matt sometimes floods my mouth with a slider when I suck his dick and it's hard to swallow it all!
