Lumguzzling was a type of drinking competition that made use of the drink lum, which, while alcoholic, was impossible to overdose on. It was an activity popular in the Corellian sector, but was known throughout the galaxy.

Participants would take turns drinking entire pitchers of lum, which cost approximately 6 to 10 credits apiece during the time of the Galactic Civil War. The last person remaining conscious would be deemed the winner.
