rain man
Someone who is trying to make a business selling a shady and questionable service or product. He gets some good rep if it happens to work. If it does not do jack, he's got your cash.
Example:
''Yo bro this guy has a diet pill that can make me lose 50 lbs in a week, son. I'm totally buying it!''
-''Sounds like a rain man to me. He'll bounce after he grabs your cash.''
-''You just jealous, man."
