Hackasaurus Wretch

A lifelong smoker who continues to light up, while coughing and hacking to the point of vomiting while they are enjoying their cigarette.

Wife: Wow, did you hear our neighbor this morning with her a.m. cig? She didn't stop hacking. She sounded like she was dying.

Husband: Yeah, she's a total Hackasaurus Wretch.

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."
