A person who is so cheap that they appear to have tiny little arms like a t rex dinosaur. Their arms are too short to reach their pockets and wallet or purse. More often a girl is a t rex or t-rexer. She will never reach down to her purse to offer to pay for anything.
Yo dawg that chick is such a t rex. Every time we go out she never offers to pay for anything.

a condition in which a persons arms are shorter than the average reaching well above mid thigh usually seen with taller people (people over 6ft). Also a condition in which someone who is larger has arms that are smaller and not in proportion
if the tip of your middle finger reaches well above you mid thigh you may have t-rex arms
