Pertaining to rum: What do the initials O.P. stand for please?!
Answers: Over proof. It's a rum with a 150 proof rating or so (Bacardi 151 for example)-- and it's at least 75% alcohol. Normal Rum is 80 proof (40% alcohol.)
O.p stands for Out of Place..
it means 'Over Proof', which i think means over 40% alcohol
