Daadult
Daadult is when dababy grows up and starts acting like they know what they're doing. They still say 'Let's go!' but now it sounds like they're trying to sound cool.
'Let's go!' said Daadult, while tripping over a couch.
'Let's go!' he yelled, then immediately fell into a puddle.
'Let's go!' he said, then got lost in the mall.
