What does *what's your ask?* mean? It's the first time I heard people use 'ask' as a noun, so I'm really confused. Thank you.
Happy student*what's your ask?* "What's your ask?"
Use ". Not *.

It sounds like "What's your question?" but it's wrong in standard English. It may be an English learner who wrote it, or it may be a bit of new slang (which I don't recommend you imitate).

Prevalent in my industry at the moment I'm afraid (IT), "What's the ask?" Meaning "What is it they want us to do?" Hopefully a piece of jargon that will have its day and then fade away.
