no-way-out talker 

A no-way-out talker is one who sparks up a random conversation, and talks endlessly regardless of your interest or obvious impatience. This person talks non-stop about anything and everything and asks a lot of questions to trap you. A no-way-out talker can be a total stranger you happen to meet in a common area, such as a shared laundry room, or a co-worker. This person makes it extremely difficult to end a conversation.

No-way-out talker: Hello there! Oh laundry's always fun on a Tuesday night. I'm new to the building. I'm a customer service rep but looking to get into something creative. What do you do? What is your name? I like Burrito Beach. I eat there about three times a week. I think it's always so fresh and delicious. My cat likes it too. How about you? How long have you lived here? Do you have any pets?
