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.

momasaurus rex 

control freak of a mom with a t-rex attitude of...a great big head and little tiny arms to try to control everything by telling you what to do but failing miserably.

My momasaurus rex thinks she is helping but every time I turn around she is screaming her word vomit all over me and trying to control my life.
