Sepp Blattered
To get unbelievably drunk. So drunk you make awful decisions, mostly for the benefit of yourself and no-one else causing utter turmoil to many people around you. You will become a complete and utter arsehole, talking about topics you have no knowledge or passion about.
Example:
Guy 1: "What you up to tomorrow night"
Guy 2: "Mate I'm getting Sepp Blattered... Christ I don't expect to see tomorrow"
Guy 1: "What you up to tomorrow night"
Guy 2: "Mate I'm getting Sepp Blattered... Christ I don't expect to see tomorrow"
