look up any word, like donkey punch:
 
1.
Popular Brit affirmation - a form of no-bullshit total agreement.

The term " DeadRight " was 1st coined when the Founder and Owner of "WHOR_NET" posted a sign on his property
which simply stated "IF YOU BRING THE POLICE TO MY HOME, I WILL SEND THEM TO YOUR'S".
The purpose of the sign was to cause Visitor's to keep themselve's and thier action's in check.
The Underlying Logic has created a ripple effect thruout police infested hood's whereby Snitches, Informant's, Sting's, Set-up's, and Property Seizure's are rapidly Disappearing due to the absent's of street dealing's of Drug's. Finally the best result of the DeadRight Rule is that Rumour's and Street Talk is null!
I heard so & so was a Snitch! No way! He's DeadRight...
