"The nerve!"

Someone had the nerve to finish up the water in the cooler, and instead of changing with a new bottle, he/she (more likely she) just dragged a new bottle and left it at the feet of the cooler.

(Meaning to expect the next person who needs a drink to change the bottle.)

TMD.

And don't give me the crap that girls cannot change a bottle - then what for spend so much money to go Yoga or Gym!
