EDW Lynch:
I live in a walkable San Francisco shopping district that has the extraordinary misfortune of being the prime hunting grounds of the face-to-face street fundraiser. I prefer the British slang, however: charity mugger or “chugger.” A chugger is a fresh-faced 20something who waves and shouts at you like a long lost friend, and then demands you give money to Charity X.
Chuggers use extremely sly verbal jujitsu to rudely barge in on your neighborhood stroll, walk to work, or private conversation, and paradoxically make you the one who ends up feeling guilty and apologetic. And you might even hand over your credit card.
