Why this rock is probably not a meteorite:

It's full of holes. Meteorites don't have holes (vesicles) like this.
 
What is it?

This is a terrestrial basalt. The top of this rock has a dark, glassy coating that resembles a meteorite fusion crust. Such a coating forms at the surface of a cooling lava, however. Meteorwrong no. 18 has a similar coating.
