Water cooler roulette

Water cooler roulette
A game I invented to play with my bored co-workers at the office.
Two people take turns pouring water in a

cup from the water cooler.
One can pour as much or little as they want.
The goal is to not make the air bubble inside gulp.
Taking turns until someone makes the air bubble gulp inside and loses.

You messed up like water cooler roulette.
