When two men who's ethnicity ends in the suffix "ish" (ie: Irish, Polish, Jewish, etc), engage in a specific type of 3-way with (usually) a woman. One man copulates orally, while the other vaginally or anally. This, in effect, skewers the woman like a Shishkebab. It is also variantly spelled ishkabob.
