Trans Fat

Alright, listen up, you silly goose. You see, you made a joke by playing with the word "trans". You know, like, you took "transgender", which means someone whose gender identity is different from the sex they were assigned at birth, and mixed it with "trans fat", which is like a type of unhealthy fat in food. And voila, you made a silly pun with words! Not that hard to understand, is it? You still have to learn a lot about the world, I hope this bear explanation helps.
