Someone who resolves most confrontation through biting
Oh god the horror, Grace just hit that kids face off when he called her a smellbag. What a T-Rex head.
When someoneâs really aggressive but have nothing to back it up like the noble T-Rexâs stubby arms. Also they might bite you.
Wow did you see Grace the other day when she couldnât win the fight she bit her, what a T-Rex head.
