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!
Me: You're the fucking shitmaster dude... mad props. Now go clean it up.
Originally from Sapporo, Japan, a shidmaster is a specialist in retaining huge amounts of bowel encrusted fecal matter for weeks to months as a form of meditation.
Shidmasters in India are known to be able after months of non-functioning bowels, give themselves, only through anal suction, deep colonics to release the dangerous build up of waste.
"Hey, I'm not sitting around that guy; he looks bloated and is definitely a shidmaster looking for some weird fun"
"Hey Shidmaster, drop me a few nuggest of shid"
Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
