pivoplech rulez? what does it mean?

[d56112002]

I found this easter egg location laying branches that shows capital letter : pivoplech rulez.
What is that exactly mean?
I don't know čeština, through google translation I know "pivo" is beer, ''plech" is like tin metal?
and "rulez" is roll ?
So "pivoplech rulez" means something like six pack or a dozen beer?

Just found it now! If you go to the edge of the map there's a Skelton holding a tree too! Maybe 20m north.. can't reach it as it's just outside the boundary..
