Jaasome, originaly spelled JAWSOME originated from the Street Sharks mini-series cartoon which aired on TV in 1994. Why would a shark day awesome when they could instead say JAWSOME?
You know like when you throw a shark-themed party then get plastered and super excited about unicorn horns, and then have to exclaim that it's an amazing party. "JAWSOME"
Dude: I went to the craziest party last night.
Guy: How crazy was it dude?
Dude: It was FUCKING JAWSOME
