Shortest form of what's up? Origins of word come from the streets of Brooklyn when a HS fight in 1994 between two thugs occured, one thug speaking out of rage said quickly whatta, the other responded w'up son w'up son!
W'up son? W'up w'up.

Wup is Wuppy for short. An exclusive nickname only to be used for close family members, friends, pets, or people of important significance. Only a select few humans are even allowed to call people this sacred word. Anyone else shall be shunned.
That wup called me up wanting to hang out, I was happy.
