It'll sound stupid to a lot of people because of how ubiquitous the term Jumpman is (and because that's the official term for the logo straight from Nike/Jordan Brand), and that's more letters and syllables than just saying Jumpman; but whatever floats your boat my g.
What about when some1 has on a pair of fakes and you tell them "why does ur jordanman have to left feet" or "why does ur jordanman have extra fingers" wouldn't that be how u say that?
