Ambiturner
context and source: The title character in the movie Zoolander can only turn around in one direction; he wishes he could turn both ways, which would make him an ambiturner.
composed of: ambi + turn + er
apparent meaning: able to turn around both ways

Due to Left-sided Extinction, I am typically not an ambiturner. This is also why I shouldn't drive a Mustang. But I want one so badly.
