Giant Fucking Robots 

A saying that can be applied to any situation, but is most often used to express surprise. Similar to "Oh my God!" or "What The Fuck?" in its usage. Can be shortened to GFR.

(May never be used to actually describe giant robots that are engaged in sexual intercourse.)

"The dog just pissed all over the carpet."

"Giant Fucking Robots!"
