One option - Let the girl disqualify him herself.
Say something like "Woow you two look perfect for each other, I should let you two go (to the girl)."
If you've built any sort of comfort with the girl it's unlikely shes going to be happy about being left with loud mouth douchebag and she will make some sort of objection which you play upon / emphasis.
Can't remember who I got that one from but it can put an AMOGs tail between his legs if the girl objects hard and then moves closer or puts an arm around you.
