Someone, usually female, that is trying to seduce money from a poor person. Effectively, a very low level gold digger attempting to work someone already poor. Instead of extracting money and expensive gifts from a wealthy person, they aim low and attempt to get meals and drugs from suckers. Sometimes they're completely unaware their prospective victim is broke.
"So you paid the prostitute your last $50 and she ran off without fucking you? What a dime digger!"
