Variation of the expression "Beer under the bridge", however typically applies to two or more girls who have had too much wine and get into childish, irrational fights.
My girlfriend went on a girls' night out Friday and they all had too much wine. She came home hammered and was crying about some sort of ridiculous argument on the colour of some girl's dress. I said to her "forget about it, it's wine under the bridge".
