This is a question Im curious about
Lets say you're at a party and some dude is hitting on your girlfriend, she is laughing at what he says etc..
What are some witty / clever ways to AMOG him? Withhout like getting into a fight ...
something more intellectual, that would just leave him ashamed, and he'd walk away?

if your relationship is fairly stable and you've been seeing her awhile I feel the best move is just to ignore it and go talk to other people at the party and have a good time. You may come off as threatened if you try to go out of your way to sabatoge any convo she's having (and might cut him off creating a kind of attractive mystery to him). Just tell yourself that walking out of that party with her by your side knowing she'll be going to YOUR place is the best AMOG in my opinion.

Parties aren't ideal for long-term couples and if you go to one you have to learn how to kind of separate and mingle with others, that way it doesn't feel like just another night in with the 2 of you (with other people around)
