Similar to the cock block, but relating to an object (animate or inanimate) obstructing the ogling of a sexually desirable human (one would hope)
Tom was trying to check out this girl at the bar, but was being "gawk blocked" by her pontoon like friend lumbering in front of her.

A gawk block is a plastic rectangular tool with a rectangular opening in it on one side. It is usually used in Marching Bands by striking over the side with the opening with a drum stick to produce a loud and piercing clicking noise, called a gawk, to keep time for the band by the drill instructor or drum major.
It is very irritating when the person keeping a beat on the gawk block passes very close to you, because it hurts your ears.
