Someone who owes you $.72 USD.,
or a way of saying mother fucker around adults without spankings.
"That kid is a mudapuk, right mom?"
Someone who is very money hungry. They demand overpriced rides and are always looking to cheat you out of a few dollars (or cents).
That guy is such a mudapuk, he charges me $5 a ride when it should only cost $3! Also, he is angry about 72 cents!
