Can I tell my wife that upcoming guys night out is still for guys when another wife was invited?
Why would you want to alienate the wives?
I just want to be a dick to her.
You need to be more honest with her. It's bad to start lying to your wife about things like this she won't trust you if you do.
I don't care. I'll lie and I'll be happy.
Rather than making up an excuse for a guy's night out, maybe you and the guys can just hang out separately and have the wives unintentionally have a girls' night out. Then it's a win-win situation and you can be yourself with the guy without having the wife butting in.
