dime hawk

Dime hawk is someone who stands around at a certain place, (i.e. Street,stoop, porch, looking out a window) with the sole purpose of buying a dime bag of pot. Usually the dime hawk doesn't have enough money to buy that pot. So they beg everyone that they see for a dollar.

Me: That dime hawk just got me for a dollar
Mike: Why she need more pot, she just smoked all mine an hour ago
Me: Really? That dime hawk is such burn out.
