Adulting 

Being a responsible adult. Used by immature 20-somethings who are proud of themselves for paying a bill.

So tired from adulting! I went to my 8-5 job today! Look at me!

the act of being an adult; to do things your parents would normally do, but they aren't around, so now you have to do them whether you know how or not.
