Tagasaurus Rex 

Someone who far too regularly tags photos on Facebook at every possible occasion. These photos are usually unwanted.

Izzie: Hey Phil and Dan, that girl Holly Rodrigues has tagged another Facebook photo of you.
Phil: For fucks sake Rodrigues...
Dan: That girl is such a fucking Tagasaurus Rex!

Lameasaurus Rex

1. The King of Lame; one who chiefly thrives off the disappointment of others.

2. The anchor to all things enjoyable and happy.

Herbavores are having a party. Great beats provided by DJ Stegasaurs. The tree bark Chef Triceratops made is so tasty. Yo my boy Pteredactyl I haven’t seen you is so long. Dramtically the door swings open and it’s my roommate. He’s brooding with emo overtones. He pulls me aside and asks that the music gets turned down and everyone he doesn’t know should leave because he doesn’t trust them. Also, he can’t stay up late with me because he has to rock climb with his new Omnivore friends. I return to the party. "Who’s that?" they ask me. Oh, that’s just my roommate. He’s Lameasaurus Rex.
