This woman on the TV is saying that everyone you know should know that you're single, available, and willing to be set up, just in case they know someone with whom they could set you up.

If I had ever allowed that to happen, I'd have ended up with a gay man in his early twenties (who, mind you, used to call me Mia - after Mia Farrow), and only because someone in my family thought that 19 was too old to be a virgin.
