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.

Imagine this scenario. It's cold outside, and you're wearing a half-sleeves shirt. To get your arms out of the cold, you pull your arms into your shirt, with only your hands poking out of the arm holes. That is called T-Rexing.
The weatherman said it would be 80 degrees, but it was so cold I had to resort to T-Rexing the entire time I was outside.
