fascist rainbow

A flag in the pattern of the US flag, but all the colors changed to black, grey and olive drab, except for a blue stripe, a green stripe and a red stripe.

I wasn't completely sure that my neighbor was a jackass, until he took down his regular American flag and put up a fascist rainbow instead.
