Vaginasaurus Rex 

1.When someone, male or female, is being an incredible whiny bitch and/or seems like they have so much sand in their vagina;real or presumed, that the Mojave Desert then seems like a sand box.

Their mating call is a sound that comes deep within your throat, is loud; above 80 decibels and you have to wag your tongue back and forth in your mouth to create said noise. Since their nature is to wade in their own self pity, instead of being turned on they reply with "What's wrong with you?" or "You're so fucking gay". And then walk away to go and touch his/herself.

Greg: "Dude, you're such a Vaginasaurus Rex"

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
