 While on the road, "Stone Cold" Steve Austin (IV) (qv) decided to  call Christian (Jason Reso (qv)). He left a message on Resos  voice mail, that was completely unclear. When Reso and Austin were  talking to each other on the phone, Austin kept saying "What?" With  this, Austin decided to use it as his catchphrase, and it as well as  became a popular catchphrase to fans as well.
