Fuckfaced
The PINNACLE of the drunkenness scale, far more than ‘drunk’ and certainly levels higher than ‘wasted’
One is only well and truly fuckfaced when they can’t stand up, let alone walk…

The less you can talk, the more fuckfaced you are
‘I want to get well and truly fuckfaced tonight’
‘Brad is such a lightweight, he was fuckfaced after 3 drinks!’
