Malt liquor. Evil stuff.
I was probably 12 when I discovered that a hot 6-pack of Schlitz Malt liquor Bull tallboys will absolutely kick your ass.
Unfortunately it was just a discovery and not 'the lesson' it should have been.

I'll occasionally grab some Mickey's Big Mouths though. Miss the old style tops, but, tossing back a few 'hand grenades' still has some nostalgic value for me.
