When you are at a bar and someone taps the top of your beer bottle causing the beer to foam up and overflow and piss that person off. It then proceeds to start a bottle tapping war throughout your group. It never ends. The best solution is to put your thumb on the top of your beer bottle.
"Dammit Katie just tapped my beer bottle. Now there is beer all over the floor and my shoes. Shit I hate bottle tapping."
"Katie, stop bottle tapping everyone!!!"
"Katie, we are never going out with you again if you continue to bottle tap us!!"
