What do you mean ? You can use proper names for what I think you mean.

What are you talking about and how old are you?

"it" refers to?

I'm really not sure what you're talking about. Could you please use the proper term for what you're trying to discuss? We really can't guess, we need to know, and the more information, the better. Just don't use slang and the system won't edit out your word. Use the correct term.
