a new way to say dece, a shortened form of the word decent. If you ever say decearoonie out loud I promise all the cool kids at school will not kill you. Just remember I cannot be held accountable for a severe beating after you say the word decearoonie.
Cool Kid: That switch kickflip to nosegrind to nollie wallride stall I just pulled was pretty sweet.

Wannabe Cool Kid: Yeah, it was decearoonie!

Cool Kid:Wow, the urge to kill you is ubelievable right now.
