Hi Couch Potatoe, When I hang out with my friends it is that we are together, chatting, perhaps going for a walk, stopping a the cafe and drinking tea or coffee or beer. chit-chat, nothing serious or planned.
(Now, Here is where I get creative) : hanging out by the spoons and/or ladles to me could mean in someone's kitchen or in a restaurant. I am probably way off but that is the feeling I get.
