A Portmanteau of the word
professional and the term Hobo. It implies
someone who is so effective as an unemployed
bum that they appear to be an engaged middle to upper class citizen.
Anna is such a probo. She is always begging her dad for
money, bumming drinks from her friends, and selling clothes. She
never works but at least she bought me some groceries with her food stamps and gave me a ride to work in her 2003
Mercedes.
