Hack to Slightly Increase The High Five Gesture?

[SimCoffee]

Once my sims returns from a vacation, they're constantly giving each other that local 'hang loose' gesture, which is fine with me. I live in the US, however, where the 'high five' is fairly common and more fun and often related to playing sports. Think "basketball".

Can you make a hack which slightly increases friends will do this autonomously? If you could do it as a greeting between male friends only since it is more of a 'guy thing', that would even be better, but if not, just random high-fives between friends regardless of gender is fine.

I have all EPs. Thanks for your consideration.
