momasaurus 

over protective, yet micro-managing mother who uses guilt to try and make you change your mind

Everytime I try to explain to my momasaurus my future plans she gets upset and then tries to discuss how if I do it a different way my life would be easier.

Mika (Mikasaurus) 

The most amazing non-professional singer in the entire universe. He is also the last remaining Mikasaurus in the entire world. He's really nice and funny and awesome at everything. He will completely deny these facts because he's too modest. He's amazing and I love him. (:

"Where is Mika (mikasaurus)?"
'Off being amazing."

Mansaurus 

A comprehensive tome of reference and learning on how to be manly. For some, manliness doesn't always come naturally, and the Mansaurus is an essential guide on how to behave in a manly fashion, use manly words spoken in a deep manly voice, and use one's body language to show how manly one is. Many famous manly celebrities allegedly have a copy tucked away including Chuck Norris, Daniel Craig, Russell Crowe, Madonna, Pink, and Fergie from the Black Eyed Peas.

"Daa, I knew I was in love with her da moment I saw her Mansaurus fall out of her manbag as she lifted her leg to fart"
- Sylvester Stallone reflecting on his marriage to Brigitte Nielsen

Mamasaurus

Similar to a Mama Bear, the Mamasaurus will protect her little dinosaur in every way that she can. This can be anything from burning your hand on the stove to defending you from a bully at school. Mamasaurus has got your back!

You better leave me alone or my Mamasaurus is going to get you!
