"And if it feels so good it can't be wrong"

I wonder why that phrase is in there. Does it suggest that getting drunk and banging chicks is wrong?

fifth of vodka is 1/5th of a gallon, about 750ml. drinking that much and you are still feeling good would definitively make you feel that it can't be wrong. If you don't feel good it probably was a bad idea.
