Why this rock is probably not a meteorite:

1) Meteorites usually have smooth surfaces. If an object like this came through the atmosphere at the speed at which meteors enter the atmosphere, all the knobby places would be the first parts to ablate away.

2) It's got vesicles. Meteorites don't have vesicles.
What is it?

It resembles a piece of slag.
