Sick is basically the same as whatever was the cool terms to use when the average person on here was a kid. I haven't read The Great Gatsby recently so I can't give you a precise example.
Sick means good. A lot of negative words have positive meanings, but you don't see it the other way like if I described this post as both riveting and entertaining. Doesn't fly as slang.
The Beast is my favourite. Looks jolly but could also crush you into dust. They make a bit much of the woman being all big and ugly at times, it's not nice.
They go largely by smell, but of course they just got bored of Glenn under the bin so just mooched off!
It was a bit limp, felt like the episode leading to the finale rather than the finale itself.
