second choice hamster

Someone that you would hook up with when you can't get with your first choice. The name is a reference to when you were a little kid and you went to the pet store and you wanted something cute, like a puppy or a bunny or a kitty, but your mom said NO, so you got a stupid little hamster instead.

He's totally my second choice hamster, so I only went to see him for a few minutes after I got with the guy I really like.
