I drink quite a bit, and if an average office worker drinks 3 to 4 bottles in 2 hours, they're basically top-tier

Usually, we start drinking around 7 PM, and on very rare occasions, we go for a 3rd or 4th round, moving from place to place until 2 or 3 AM. By the 2nd round or so, I can already see everyone starting to get tipsy lol (actually, these days, that rarely happens)
People say things like, "I think I drank 7 or 8 bottles of soju," while being completely delusional.
That is almost 100% a lie.
When I join new groups of people who claim to be heavy drinkers and drink with them,
if they drink about 3 bottles per person in 2 hours, most of them (since alcohol content is lower these days; it would have been about 2 bottles back in our fathers' generation)
get a heavy buzz and feel terrible the next day lol
I'm a heavy drinker but I don't show it, whereas most people tend to boast about their drinking capacity.
(I haven't met any thugs or top-tier athletes, so I wouldn't know about them, though.)
