look up any word, like sex:
 
1.
something that is so good ( delicious ) it's sick. Sick meaning good. So sick, it makes you feel funny, but you like it. Something so good you hate it, but you still have to give it props.
Damn!... That's Sick Delicious.

Did you see that shit!... that was Sick Delicious for sure.
