Adultalescent

Tiffany's mom bought us beer and then she spent the night driving us to parties and lying to our parents about where we really were - she's SUCH an adultalescent!

adultolescent 

Your young adult roommate/friend who by all rights should be thriving at attempting to make a living in this world, but instead lives in your home and leeches off you constantly. Can't be bothered to find a job, make any money, clean anything or regularly contribute in any meaningful way. Fully expects you to take on the parent role and take care of them because "life is hard" and "its hard to find a job". Doesn't understand bills, cost of food, or responsibility of any kind.

Leech: I applied for a couple jobs a while ago but haven't heard back yet. Did you buy groceries yet? Are you going to make supper?
Me: You are such an adultolescent. Get a job!
