they stacked the glass up + right up to the level that you would normally have if you had ice in your drink anyway + and consequently I got ploughed

"I said are you allowed to drink? You know, beer. Whatever. Isn't it against your religion?" […] There were a few kids at school who said they were Mormon, but that didn't stop 'em from getting ploughed, and other kids who went to church but smoke and drank and cussed and screwed.
