Said when a guy who hasn't gotten any in a while strikes out with another girl. Refers to the opening of a jar of peanut butter for the purpose of slathering said peanut butter on one's penis to provide a dog incentive to lick it.
Sexually frustrated man: "I just struck out again! Such a long dry spell..."
Friend: "Might be time to open the peanut butter"
girl a) Why can't i open happiness? I'm 16 and a half
girl b) it's our alco-laws; I think they should make the North American alco-laws like those of the European Union. Drink beer, wine and maybe rum and coke- since rum is usually dark and Coca-Cola is black and nobody will know the difference- at 16, and heavy liquor at 18.
