verb. 1) to tell someone to "chill"; relax, fall back. 2) commonly used to shut down a stupid remark or completely end a conversation. 3) also used to completely shut down a stupid action another person does. 4) a more stronger form of the verb consists of a double back; i.e. "BACK BACK!". this phrase originated out of the vicinity of Mt. St. Joseph High School in historical Irvington, around the period of 06-07 school years. Its popularity has grown and continues to flourish amongst the Mt. St. Joseph Community and is begining to spread at a rapid paste. Although to term's weight itself is hard to grasp, one must take time as practice to completely master its effectiveness
