Why this rock is probably not a meteorite:

The smooth glass skin on this rock is on a flat side.

The rock is full of holes. Meteorites don't have holes.
  
What is it?

This is another vesicular volcanic rock, probably a basalt. When lava is erupted, the surface in contact with the air cools first, making a glassy surface. Because the lava is a liquid, the top surface is mostly flat. See also meteorwrong no. 018.
