look up any word, like fleek:
 
1.
when a company releases a script/program they have code in the scripts that call back home after u have installed it!

therefore the company can see who u are and whether u bought the script or not etc.

to null a script is to take away the "call back" so that u dont get in dog shit for installing a script that u didnt buy! hope this helped???
Person1: Cool I Got Hivemail
Person2: Wont you get dun in for that stuff?
Person: Naw, its nulled
