deadcheecks

Seriously; to reference something being accurate or on point.
Used similarly to the term 'real talk'
Believed to have originated in some Harlem neighborhoods in NYC as an evolution of the term 'deadass' which is used in the same way.

"The song that's playing is ILL!"
"Deadcheecks."
Or
"You had to be there, man! That guy was like the Hulk, deacheeks!"

Deadcheck 

The action of checking if a friend/roommate is still alive after not seeing them for an odd length of time.

Guy 1: Have you seen Bob lately?
Guy 2: You should probably call in a deadcheck.
Guy 1: Nah, maybe if he's not back by Monday- I think he went to Vegas.
