When during the process of calling the shotgun seat in a car, if a second party calls "blitz", the first party may then call"takeover", which enables him to use physical force to reclaim his rights to the shotgun seat.
Calling "takeover" renders any subsequent call of "wizardry' null and void.
John: "Hey guys, lets grab lunch, we'll take my car."
Ben: "Blitz!" (proceeds to sprint to the car like an annoying little kid)
Mark: "Takeover!" (Pushes Ben out of the way and gets into front passenger seat)
Mark: "Shut up Frank, u can't use wizardry after someone calls takeover, and its a stupid rule anyway."
