"Wallet Slap- When you whip out you phatty bi-fold and slap that bitch across the face.  

 The practice of wallet slapping started on Oct 5 2005. It originates from this one kid hitting this one other kid in the face with his phatty bi-fold and yelled ""You just got wallet slapped BITCH!"" 

 **A tri-fold will work just fine but to get the best slap a phatty bifold is    recommended. NO not a regular bi-fold but a PHATTY bi-fold 
  	  
 The proper technique for a good wallet slap is really quite simple. All you do is take your bi-fold, open it and grasp one end firmly in one hand. Then you take it and you slap that mother fucker across the face with the free end. This technique will get you the best slappage 

 Now little kids go and steal your daddy’s wallet and go around wallet slapping those mother fucking bullies up side their heads"
