To be sick (adjective) Cough cough sneeze sneeze…no not this kind of sick. If your buddy says that the party was sick he’s saying he thought it was really cool, awesome or the best. In this case it has a similar meaning to the wordawesome, however, you probably will only hear teenagers and college students saying this – oh and maybe those Californian surfers!

“Yeah, a few times, it’s sick!”
Example 2)

“Oh, man, I knew I should have gone!”
