The term jerkoffasaur comes from combining "jerking off" and "dinosaur". Because dinosaurs are ancient, death and big different meanings apply to the term.

Meaning:
1. Being considered too old to masturbate.
2. Being unable to jerk off, like for example a T-Rex who couldn't masturbate because his arms are simply too short.

3. Dying from too much masturbation or being found with the deceased's hand touching the genital area.
4. Being a big jerk, the size reference can apply to both the size of the subject or the severeness of being a jerk.
1. "He's 40 and still living with his parents doing nothing more than jerking off..." "Don't act so surprised, didn't you know he's a jerkoffasaur?"
2. "He broke both his arms, the poor jerkoffasaur."
3. "He jerked off so many times that he died, what a jerkoffasaur!"
4. "My boss is such a jerkoffasaur that he had me working all weekend long!"
