look up any word, like pussy:

Wine Math is when you split a bottle of wine and the other person drinks more of it than you, then assumes that you are as tipsy as them.

The more they drink the tipsier they get and the soborer you are, no the other way around.
My girlfriend and I split a bottle of wine, I only had half a glass and she had the rest so she assumed I was too drunk to drive. She cannot so "wine math"!!!
