A mooelcher is a combination moocher (someone who is continously sponging and living off friends) and welcher (someone who routinely reneges on debts, especially debts owed on bets or wagers they just lost).

Properly pronounced the moo - is empashized much like a cow mooing as in "mooooooelcher!"
George rescheduled that dinner he owes us again. And then he hit me up for a cigarette even though he 'quit' smoking. What a moooooelcher!

The motherfuckin mooelcher just told me to add the twenty bucks he owes me for the Patriot game to the hundred he borrowed last week!
