Look at this! I'm going 20 under because of the wreck on the other side of the high-way. I've been gawk blocked.

Gawk Blocker 

A person or thing that obstructs one's view of a point of interest, particularly the view of something sensational or astonishing.

"Hey, down in front! That dude is such a gawk blocker."

"Did you see that chick's rack?" "No my girlfriend was in the way. She's a total gawk blocker."
