Use your hand to check the damage

When Waylon randomly glances over at the bar you quickly lift your bottom slightly off the chair and run a hand along it. When your hand dips into a warm puddle trapped by the bowl shape of the plastic chair you realized the severity of the situation. You are completely soaked and still have to pee, but don't want to walk across the bar to the bathroom with your pants in this state.

You wipe off your fingers on the leg of your pants and settle your butt back into the warm puddle on the chair.
