A liqaholic is someone who can drink a insane amount of hard liquor (hense the liq in liqaholic) A liqaholic has a liver that could digest straight nails from its years of indulging in 151 and hand sanatizer. This is the type of person you wouldn't want to go shot for shot with because utter defeat is as guaranteed as is your alcohol poisoning.
Person 1: did you see that person just take 4 shots of everclear?
Person 2: YA, even Stone Cold Steve Austin 3:16 couldnt do that! They must be a liqaholic!
