MM certainly has the PG role down. Bossy and dropping the elbow like a hammer, that's MoJeff for sure. And I guess "Alouette" was what the band was playing when UConn played Louisville the last dozen or so times.
As to origins of "Muffet," apparently a nickname cooked up by a relative and bandied about in the family until it becomes established as the real thing. Happens in Irish families, and others too, as I believe Mookie Wilson of Mets fame got his name the same way. This is why we often hate our relatives.
