blind charity

Giving money to people you don't know, for a cause that probably doesn't exist.

I.e. "Help me save my dog," "I need money for gas," "My child is in the hospital"

Random Stranger: "My child is in the hospital, please help me raise money for him/her"
Me: "Have any pictures of this child?"
Stranger: "Not on me"
Me: "Right... I'm not one for blind charity"
