Essentially a monster costume. Often of either mythical or created characters. ( ie - werwolves, dinosaurs, lizards, gargoyles anything more "monster" like) Some resemble fursuits but rarsuits are never "cute" or try to be anything of such. Nor are they remotely related to sex. They often resemble monster suits that would be seen in movies and such and many agree that they are cooler than fursuits though they are not as widely known.
"Alot of fursuits and cosplay is lame. Rarsits on the otherhand I admit I find more appealing. Why be some stupid giant stuffed animal when you could be a scary werewolf or something?"
"Part of the reason John got a role in that indie horror film was because he owned a rarsuit and offered to play the monster character"
Rarsday (n.) The day of the week that lies between Wednesday and Friday. In scheduling abbreviations, the days of the week are often indicated as "M T W R F." The day between Wednesday and Friday, therefore, is often referred to as Rarsday.
Referring to this day as Rarsday instead of it's traditional moniker, Thursday, generally indicates drinking, tomfoolery, shenanigans, merriment, and other bits of debauchery.
I just woke up next to three hookers in a pool of my own vomit with coke scattered all over myself and a new dick piercing that I have no clue how I got. That was one hell of a Rarsday.
Australian slang term used to imply that someone is completely crackers. An analogy used to convey a state of insanity, possibly catalysed by heavy consumption of legal or illegal substances.
