yackasaurus rex 

Someone, typically a female, who takes 10 minutes to give you a simple answer. A chick you meet at the bar and find out her whole life story before your beer comes. A derogatory name to call someone when they are rambling on about nonsense.

Stay away from Yackasaurus Rex over there,...shit, I met her three minutes ago and I know more about her than I know about your mom...and me and your moms go back, way back.

Hawkasaurus Rex 

ANIMAL: This animal has been discovered taking over males in particular. Some consider it a form of a hair cut. Others see it as an animal that eats peoples skulls and they consider it a style. It certainly is not, so do not be fooled.

Guidos. Hawkasaurus Rex.

Whackasaurus Rex 

When a person or situation is so immensely whack, that the simplicity of uttering "that is whack" does not suffice. The level of whack is so monumental, and so infuriating, that only the grand stature of "Whackasaurus Rex" can do the situation justice. A tyrannosaurus rex is a monstrous and violent dinosaur, and so the correlation makes sense when someone or thing is monstrously and violently whack.

Individuals that are classified as Whackasaurus Rex, have also been known to be perpetual users of Awkward Sauce.

You see Johnny kick that little girl in the stomach?

Yea, Whackasaurus Rex, man...
