Another term for beautiful breasts. Much like headlights however when dick beacons are present all penises become erect. Hence the beacon calling out and they answer.
Guy 1: How did the presentation go?

Guy 2: Not good. The instructor had the Dock Beacons showing and I had a pitched tent the whole time and couldn't hide it.

Guy 1: Yeah man her dick beacons are weapons of mass seduction.

Get the Dick Beacons mug.
Generally used as a name for really nice breasts. No matter the size. They are so perfect they cause uninvited erections. Sometimes at the worst moments.
Guy 1: Hey man how did the presentation go?
Guy 2:Not good, I couldn't take my eyes off the instructors dick beacons. I couldn't lose the hard on at all. Just did it with a pitched tent.
Guy 1: Awe man now I'm pitching one from you talking about her dick beacons.
