DEADASS 

Short for "Dead ass serious" and "I'm dead ass serious too." East coast street slang that made its way west and online. I watched 3 guys say it on reddit, the 4th asked why is everyone saying 'dead ass'? He immediately got thumbed down by every nerd up in that sub. "I'm dead ass serious too."
