Adultinger
Adultinger (noun): one who does adulting when there is no other option (and perhaps not even then). See Adult, Adulting, -er.
An adultinger is not an adult (who performs as an adult by definition), but someone who goes out of their way to point out the adult things they are doing. They refer to this as 'adulting', as in,
"I'm adulting hard right now." or
"I can't deal with adulting today."
Adultingers may look like, even sometimes (when they're not whining) sound like adults, but they're really just the 'Baby Huey' of the adult set.
