You fucking people are crazy.
If he's that much of a friend, then you don't say ANYTHING. You just smile and forget it. The only mission that day is getting your friend laid. Period. Of course you can have a talk with your buddy later to discuss what a whore she was/is, but getting laid is job #1. At least where I come from.
Alpha male...pussy... bitch.... wtf? If you're that good of friends, then you know each of you are cool. discuss it later. Don't ruin his day, today. But that's just me....
and my firends.
