I saw this from this article. I feel the word 'sick' means something good here. I found a definition in this dictionary:
very informal very impressive, attractive, enjoyable, etc. This word is used mainly by young people.
The hair, make up and outfit is sick! She looks amazing!
(Macmillan Dictionary)
I'm not sure if I understand it correctly. 'Sick' can also mean unpleasant. How can we determine if the speaker means good or unpleasant?
