look up any word, like fuck boy:
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.
