Question about getting drunk?

I don't have a lot of experience in this field but, my sister is always a parties. I personally don't think ur body fat really matters cuz my brother had 5 % body fat and he is not a light weight if u know what i mean. but ur since its ur second time ur probably still a light weight but in time u will be able to chug!! and the pizza thing i heard it helps to eat breads and stuff before getting wasted, like u said its supposed to help with hangovers.
