A term used to describe a person with an enormous, bulbus forehead like that of a beluga whale. Although you would think it would denote a large brain, beluga heads often look mongaloidish or retarted. That being said, most retards (mentally handicapped) and dwarves (little people) have beluga heads.
I never noticed that Rihanna was a beluga head until my cousin pointed it out. I was like, HOLY SHIT! Her dad must have been Worf from Star Trek. Rumor has it that one fateful night Rihanna was in the back a limo with Chris Brown. Rihanna playfully swept her bangs from her giant beluga head to give Chris Brown a kiss. The enormity and appearance of her protuberous forehead startled Chris and reminded him of the god awful John Travolta scientology movie - Battlefield Earth and just how retarted that movie was. Out of reaction, Chris punched her so hard that Will Smith and Tom Cruise felt it.
