Daadult
Daadult is the version of dababy that comes after too much soda and too many bad decisions. They still say 'HUH?' but now it sounds like they're mad at the whole world.
'HUH?' Daadult screamed, then threw a sandwich at a friend.
'HUH?' he said, while eating cereal at 2 AM.
'HUH?' he yelled, because the internet wouldn't let him sleep.
