bubble me in

To use this phrase you must be rather confused, not quite part of a conversation, and perhaps stood away from a group of people but listening to their conversation. If you are stood amongst people, but not listening to what they say very closely, you may ask them to 'bubble' you 'in' meaning you would like them to tell you what they're talking about and to involve you in the conversation too.

Hey Jackson, I didn't quite hear that I was stood by the bar! can you 'bubble me in'?
