TIFU playing exploding kittens with my inlaws

I had my inlaws in town for a few days and the weather turned cold and snowy so we have been stuck inside now for awhile. My in laws are from Florida and I could tell they were starting to get overran by the gloominess that Washington can bring in the winter. I (34 M) decided, hey why don't we do a game night? Everyone seemed on board, so my wife and I decided to introduce exploding kittens to her parents. Everything was going great, we were slow playing the hands to get the parents used to the rules. My wife's father seemed to grasp the concept of the game rather quickly, winning the first 3 games after an open hand. My wife is not one for losing, and started complaining that we we're all targeting her to lose first and that her dad keeps on winning. Here comes the FU. Her dad went to grab another beer, and me being a few beers in myself said to my wife and her step mom, " Hey, we should all gang bang Phil". Obviously I meant to say let's gang up on Phil but it surely came out as "we should gang bang your husband and dad" after looking at both their eyes widen followed by gasping laughter.

TL;DR: I told my wife and her stepmom we should gangbang her dad.
