A quite handy phrase, most easily used to determine whether the person you are talking to is a complete moron or not. If the person uses this phrase, or similar ones involving the words fail, epic, or lulz, the generally accepted manner of dealing with them is to kill them immediately for the betterment of mankind.

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.
That pie was made of win, lol and awesome
