[Dave bounces, springing up to take Karkat's hand in both his grubby child hands (even it's kind of hard because he's still holding the Pokéball in that hand, so Karkat's hand is kind of squished in between child hand and plasticky surface) and basically dancing in place with it. Up-down-up-down-up-up-up. He may not express much with his face, still, but his body language just don't stop.]

A cool word! A real cool word. Not like a misspellsed one, then how can anyone tell it's cool 'less they read it?

[DUUUUHHHHH. Dave calms down a little and starts walking along again.]

Should be a time word, pro'lly, 'cause on account of being a dinosaur. It's pro'lly like...a gazillion years old.

[He considers this, then notes sagely:]

So like, at least two bazillion sweeps.
