bitterspousing
The act of saying unkind, critical, cranky, peevish things about your spouse while both you and your spouse are in the company of others, often as a passive-aggressive way to make a point *to* your spouse about some trait or behavior that you find problematic, in the guise of conversing with others.
Guys, enough bitterspousing already! Let's all have fun tonight!
Jim and Cheryl ruined the evening with their constant bitterspousing.
