double under

After a long night of drinking, when you need to puke and shit at the same time, you bring the trash can between your legs while on the toilet and squeeze as hard as you can. This act can be seen as pinching a raw sausage in the middle and pushing the meat out of the casing from both ends. If severely hungover, this is the best case scenario to efficiently exhume all remnants from the night before. Male side effects from this maneuver usually cause awkward boners.
