When a chick sits between two dudes, gives them both hand jobs, then the two guys slap the chick in the ass with a tennis racket leaving behind a waffle imprint.
Aw man, last night was crazy. That bitch totally got belgium ski jobbed in the ass with our tennis rackets as she was skiing us.
The act where one person goes between two males and strokes both their penises at the same time in a skiing like motion. This can be performed by standing, sitting, or lying down.
Since there were two of us and we only had her for 15 more minutes, we asked for a skijob to save time and money.
