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...

Hard breaking ball (curving pitch) which comes in looking like a fastball, then darts away at the last second. It is the best friend of most power pitchers in the game today.
Randy Johnson and Steve Carlton have some the greatest sliders anyone can ever remember of.
