A high state of intoxication caused by drinking Four Loko. Side effects include severe blackouts, hyperness, rapid bursts of energy, sudden and extreme dance moves, and creepy dancing. Users have been known to challenge other Loko partakers to dance walk-offs and foot races.

This hybrid alcohol and energy drink was named "Four Loko" after the developers of the substance discovered that they could not go to sleep before 4AM on a night where they consumed the drink.
Dude, did you see me at the late night dance party last night? I was so loked up, I don't even remember where I went or how I got home.
