Philanthropy vs. just "giving some money to charity"

How much do you have to give in order to be a philanthropist? (I hate when my sister in law says she is a philanthropist....bitch gave like 60 bucks to some feed the children type thing)

• Oh, a billion dollar wing at a museum maybe... I always wanted a big endowment, so I donated a billion and now I'm hung.

• The introduced Mr. Golden Globes Sam Fox, son of Michael as a "philanthropist."
