That\'s a good question. Let\'s look at the word...
To orbit is essentially to revolve around something... some center of attraction, typically celestial. So... to go orbital could mean to find a regular sort of looping jam. An elliptical jam perhaps?
However, when one thinks of an orbit, like I said, it is usually celestial so that therefore makes me think of a spacey jam.
Could be referring to the orbital cavity I suppose. You eye socket that is.
I think in this case the most likely definition is
or·bi·tal (ôr\'bi-tl) (I don\'t know if that pronounciation key is right)
adj.
1: To go fucking nuts. 2: To play in a truely ser manner.
