the phelps

An intense reaction to victory or success, characterized by a flexing of the entire body and delivery of a primordial scream.

Roughly equivalent to:
"I trained my whole life for this moment and all my dreams are coming true" or
"No one will smash us!"

Inspiration: Micheal Phelps at the 2008 Olympics after beating the French in the 4x100m relay

Tom just rocked that econ exam!!! He then walked out of the building and did the phelps!!
