If you sound like a drunkard when you say things, people will not think of you as a discerning person. "AWh yeah, that game is greatttt," you say in your drunken slurs. But, really, it sounds like you think all games are great, which isn't all that discriminating of you at all.
So, we've figured out that your drunken utterances are not very discerning. But let's think about someone who is discerning. You're sitting next to a Sheikh (しき) (an Arabic leader), and boy do they sound like they know what they are talking about. Maybe it's because he's not drunk like you. He has such discerning taste, that one!
