O.P.T.L.I.F.
A loud, messy way to say Oh Praise The Lord It's Friday. Usually said when you're hanging out with your friends and you’re all wasted.
'O. P. T. L. I. F. I’m gonna dance until I fall down.'
'O. P. T. L. I. F. I’m too drunk to think.'
'O. P. T. L. I. F. I’m going to eat pizza and pass out.'
