Similar to the meaning of a person who "cock blocks," except this arrangement of "dome" and "blocker" sounds a lot cooler, than cock blocker. A person who interferes, or gets in the way, of somebody scoring on a female of their personal and sexual interests.
Hey Ryan, don't be such a dome blocker to Kevin! You know he likes Barbara and all, and he can't have you trying to steal her away from him.

Tits that look good from the outside, turn out to be nothing but fried eggs underneath the push up bra.
Check out the millenium domes on her.
