In a 3some, to settle for a handjob while your buddy gets to slide it in the hatchet wound.

When you take the fat friend out of the equation, so that your buddy is then advanced into "scoring position" with the hotter broad of the group. Essentially, being a wingman but sticking along the lines of the baseball theme.
Jake wanted to make his move with this chick at the bar, but he couldn't get her alone. I was already blacked out so I told him that I would lay down the sacrifice bunt.
