Shot Monster 

The act of taking filling two shot glasses with alcohol, dumping them both in your mouth, and then holding the glasses over your eyes like goggles and making monster noises. Usually a residual amount of alcohol will actually pour into your eyes and your eyes turn bloodshot and burn and you'll start actually screaming. This is knows as "Full Monster".

Bro 1: Rawrrr I'm the shot monster!
(vodka splashes into eyes)
Bro 1: AHHHHHHHHHHHHHH! (Full Monster)

Shitmonster 

A shit that is so massive and repulsive that there is no possible hopes of flushing it, so it ends up brewing in the toilet for days on end. The longer the shitmonster brews the stronger it grows. A key ingredient to the shitmonster is piss that has accumulated from other roomates over the days. The shitmonster eventually reaches a stage when no one can tolerate the shitmonster and the room unites to once and for all defeat the dreaded shitmonster by going on a quest to unclog the toilet. It is imperative that the creator of the shitmonster extols the final blow and slays the shitmonster.

Originally discovered at the George Washington University, the worlds first shitmonster haunted a certain group of young men for weeks. It is unknown if it is the first actual shitmonster or the first recorded. WARNING: Some shit monsters may result in death, delusions, loss of smell sight and taste and all basic motor functions.

I can't be too sure guys, but I may have just layed a shitmonster in the toilet.
