F.C.W.M - The first time you drink Monster and it hits you like a slap

The first time you drink Monster and it hits you like a slap. You hate it at first. But then you become best friends with it. That's the F. C. W. M.

First Monster hit like a slap. Now it's my best friend.

Drank Monster once. It slapped me. Now I can't live without it.

First Monster sip was a slap. Now I'm a monster lover.
