this is when you fall for a woman after giving her the manroot. she gets a good grip and wont let you go, and you dont want to because youve been pussywhipped. If you get stuck in a rootlock for too long it can lead to rootrot.
My buddy kurt fell hard for this crazy cat and she put him in a rootlock, if my boy doesnt get out soon he'll get rootrot. its a damn shame.
the definition is simple it is your dink,penis, boner, and so on it is you livelyhood it is your manhood. giving her the manroot can lead to rootlock wich will eventually lead to rootrot none of wich are good.
kurt always says "she wants the manroot"
, "im gonna give her the manroot, real rough like."
