Deadheighting

Disrespectfully mentioning someone's old height after they have changed their height. In particular, this is something done to transheight people.

Gina:''Hey Mike, you seem like a nice guy but you are short so i have to reject you''
Mike:''Short?I m 242cm tall, thats very far from short''
Gina:''But i m 155cm and you are only 2 fingers taller than me, you are lying''
Mike:''I told you Gina i m transheight, wanna see my height in my ID again?stop deadheighting me''
Gina:'' Sry Mike that i m a transphobic piece of shit. You deserve better than me. I wish you good luck finding a better girl than me''
