Adult Parallel Play 

When a bunch of people are sitting in a cafe interacting with their laptops or phones rather than with each other.

Isn't it fascinating how so many people engage in adult parallel play in cafes and then complain about how lonely they are?

Adult Playpen

Often found in a house with between 3-6 roomates within the age limits of--eh, 18-24..in a living room with too many couches. Take two of the couches and push them together face to face making a giant couch playpen. You get 4-6 people inside of the adult playpen and because it's so cozy and also a little difficult to climb out of, you end up spending hours inside just hanging out and being lazy. Perfect for hangovers and recapping the night before. Snacks and smokes welcome

On New Years Day,all I want to do is get breakfast then hang out in the adult playpen watching movies all day.
