The phrase when you can no longer hold it in and you just fucking run to the toilet. No time to waste you gotta go. This is the ultimate meanest shit of your life. At least 2 hour recovery period after. Then you gotta take a shower to clean up the mess.
One who possesses the ability to clog someone's toilet to the point of OVERFLOW (not merely backup or slow flush) causing shitty water to cover the entire tile floor and parts of the adjacent hallway carpeting. This is not intentional, and happens despite multiple courtesy flushes throughout the act leading to the final shitmastering flush.
Dave: (Running out of the bathroom) Where's your mop bro?
Me: What? Why?
Dave: Your toilet's overflowing man. Shit is literally EVERYWHERE!
