Rock block 

To cover the nakedness of some shameless hussy with the smiling visage of Dwayne "The Rock" Johnson.

When the naughty bits of an otherwise NSFW image are covered by a certain image of American wrestler/actor Dwayne "The Rock" Johnson an image is said to be (The) Rock blocked.

Poster 1: starts thread asking for the original of an image of some random actress, whose nudity is covered by an image of The Rock.

Poster 2: provides original image of The Rock wearing a tuxedo at some Hollywood party.

Poster 3: lulz, you got rock blocked!
