rack-opinion steering

Refers to how a "typical red-blooded stud" directs or "pilots" his gaze and/or footsteps in the direction of certain attractive ladies at a beach or social-gathering, depending upon his perception of how shapely the "set of twins" are that each of said cuties happens to possess.

Whenever I go out on da town in da evening to meet da ladies, I always seem to end up sitting next to gals wif perky D-cup boobs --- guess I've got rack-opinion steering!
