look up any word, like fluffer:
 
1.
My Life Is Metal.

another play on the 'My Life is Awesome (MLIA) thing. using the \m/ symbol instead of an M, so as to not be confused with any other M word or other My Life is... acronym

used when describing something brutal, 'hardcore' or stereotypically 'metal'. such as any of the things that can be found in metal music videos and album art.
'I was shredding on my guitar so hard that my heart exploded. MLI\m/.
