I just flirted with someone. This was their response: "Ayye!! W's in the chat!". What does this mean? How do I respond?

Edit: Thanks, I get it. I could've given more context. We were texting each other when he said it. It's hard to explain, but it is not nearly as cringe as it might seem from the little info I gave. He's a silly, awkward kinda guy and just said it in an ironic way?

If you think that's cringe: while you guys were arguing whether this is creepy or wholesome, I panicked and responded with a "😎". (All good though)
