Depraved Little Thoughts
or Dirty Little Thoughts
Girl 1: Look at that trail of hair going down from his navel. You know where it ends ;)
Girl 2: You and your DLTs!
DLTS stands for Driving Like Totally Stupid. It occurs when people are so stupid that they don't actually need to get drunk to mess up; therefore differentiating from DWI. DLTS ranges from mild to severe; it depends on the IQ or current mood of the driver.
Johnny: See that guy over there? He was arrested for DLTS. He was so stupid he didn't even need to be drunk.
Fred: God, what an asshole.
