To cock slap a person while said person is on the ground.

It's derived from a kid from California who was kicked out of high school for sexual harassment. His last name was Wong. He was kicked out for sexually harassing girls.

One day during P.E. one kid was running and tripped. He fell to the ground. Wong came up to him, pulled out his cock, and cock slapped him. So "to wong someone" means to cock slap a person while that person is on the ground.
James ran and slipped, so Kenny took advantage of the situation and started wonging him. James was scarred for life, Kenny got suspended.

The art of winging it in mong style. Basically having a red hot crack at doing something in a manner that defies all reason and logic. This can include actions performed by accident or without realization by an individual lacking in physical and cerebral ability and of unbelievable, inexcusable and indescribable stupidity (refer to fucktard). However, more often than not the individual is fully aware of and blissfully carefree to the fact that their actions are insanely fucked up, that they are prone to fucking up and that they have questionable mental capacity (refer to fuckmonkey or douche).
Example 1: "Fuck Trev, I know your mum is a cumdumpster but she offered to blow me. I wasn't sure what to do so I just wonged it! Man she sucks a good dick!"

Example 2: "Not sure if attaching these electrodes to my balls will fix my erectile disfunction, but fuck it, I'm just gonna wong it!".

When looking to booty-fuck someone out of your league, it is acceptable to settle for someone with the same last name. Upon booty-fucking this individual, you will say with pride, a Wong's a Wong!
I was tired of hitting on Daniel, so I cornholed David McDowell instead. Hey, a Wong's a Wong!
