Fantastic, magnificent, amazing, awesome, the shit, made of win.
Follows the theme of using 'made of *
insert word here*' as a way to describe something. Slang, usually found on the internet, although quite uncommon at present.
Although it doesn't seem to follow
English grammar properly, win can be defined as a noun, so it isn't always grammatically incorrect, it's just nonsense.
However, sentences such as
made of awesome are grammatically incorrect, but still used.
