When you take a man's penis between your open palms and use your hands like ping pongpaddles to bat it back and fourth.
"Dude,she was right in the middle of blowing me when all of the sudden I got ping pong'd. I almost starting laughing right there but I didn't want to ruin it."
when the ping is too high. Completly understandable and it cannot be debatted. If someone says "experiencing ping diff", or anything to do with "ping diff", your the last man standing buddy.
