shitmaster 

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.

Silvester

A dummm fine boy that's smart, loyal, trustworthy and caring. You'all always crave his presence. When's he's around you'll feel like your home because you can be yourself. Make sure you value him, you may never come across a boy that makes you feel so comfortable and loved. He makes you feel protected and likes to cuddle. He can get freaky too;)but while still being respectful. He has the best sense of humor by making kinky jokes. And the way he laughs will make your heart fuckin melt. You'll always find him taking a nap, playing games or on YouTube. His fine ass body, smile, his hair, you'll love it all. He's perfect. You can never get tired of a Silvester, he's the best person to be around.
