[Yumyums Inmahtumtums]

I like to keep a snap-top iced tea bottle in my car for when you really gotta go. They key is to use your foreskin to "dock" with the bottle which, in an ideal world will allow you to minimize the amount of urine that splashes onto your Tasmanian devil seat covers.

You'll obviously have to adapt the bottle to your skin-missile shape but once you get it down you'll hear a reassuring "fart" noise as displaced air continually breaks the smegma/urine vapor lock.

Be safe!
