How to respond to fellow mom asking to set up husband "playdate"?

I'm sure it's harmless and maybe said in a sort of tongue-and-cheek manner, but this really gets under my skin and I need advice on how to respond. We have some neighbors and fellow daycare parents who have become friends. The mom will occasionally text me or mention to me the idea of setting up a dads night out, or a mens' play-date (she uses the term playdate). I cringe at this framing and would like to gently push back that the men are free to talk to each other (or that she's free to set up whatever she wants but I do not want to be involved). Any advice on how to deal with this/gently shut it down or redirect? Or should I just be a better sport and help our husbands do something they should do on their own but maybe won't?
