Someone who reuses what they say to one person and then says the same thing to the next person they see in hopes that it will spark a conversation.
this is very annoying especially if it fails on you and you hear them start saying it to another person.
Example of a talk recycler as follows:
Rob: i really hope it doesnt rain today
rachel walks into room
Rob: I really hope it doesnt rain today
rachel: me too i have a party outdoors tonight. what do you have planned?
Rob recycled the sentence I REALLY HOPE IT DOESNT RAIN TODAY. therefore he is a talk recycler and that sentence was recycled
