Bean Piss

Coffee, often times used in the phrase "sucking bean piss" to refer to drinking coffee. Famously written in cursive on the windows of Starbucks locations across the country.

Riley: Why do they call drinking coffee "sucking bean piss?"
Graydon: Cause it's beans. You have to squeeze the piss out of them to get the coffee, so when you slurp it and/or suck it, you're sucking bean piss.
Riley: Yeah I mean I get that, it's just weird that they put that on the windows of Starbucks like "Hey Starfucks, Come get some Pumpkin Bean Piss".
