Barq's Root Beer

The poor man's Mug Root Beer for when you just want a large-ass $1 infinitely refillable cup from McDonald's to sit down with in the bathroom drinking enough root beer to be consistently pissing into and flooding the urinals from 3 feet away, destroy you kidneys and ruining everyone else's McBathroom experience

You know, I'm a mug fan, but damn, on any good day Barq's Root Beer's the SHIT
