An expression which appears in rage comics as a cartoonized version of Nicolas Cage. The phrase is a response to anything obvious and functions the same as "No shit, Sherlock" and "thank you captain obvious".
Some guy: I'll tell you a big fact.
Me: And... what is it?
That very guy: Stars don't blink! It's the atmosphere that makes stars look like if they blink!
Me: You don't say?

Used to describe someone who thinks they've done a great deed, charitable action or sacrifice, but in reality they've done very little to help the human condition.

Originally used under colonialism and before civil rights, this phrase expressed appreciation for honorable or gracious behavior, under the assumption that white people were inherently more virtuous. Today, it is generally used sarcastically in reference to underwhelming acts of generosity.
In Jamaica in 1765:
A: I built the slaves a church to hang out in on Sundays, even though I didn't have to.
B: Well, that's mighty white of you.
In Harlem in 2010:
A: I'm feeling so generous, I'm gonna eat my food right next to you so you can enjoy the smell.
B: Well God damn, that's mighty white of you - How could I ever repay you for such a selfless act?
