In Germany, we slap our thigh and say: "Ach, Schenkelklopfer!"

what does that mean

It's kinda cliché. It's basically that something is so funny that you slap your thigh (and maybe stand up) as a strong reaction. Most Germans don't usually do this, but I sometimes do as a joke.

if trans girls are nicknamed dolls i think trans boys should have a nickname too, and t-rex, dinasour or smth like that sounds rlly cool
