What are the “friends” doing in this picture? It’s like they’re hugging an invisible person. They’re not the only ones I’ve seen doing it. I think some of the BB Theory people also did it in a promo.
Eh. . . Hans and Franz, maybe.
Flexing
Yeah, looks like muscle flexing, not hugging.
Being goofy and I don’t think it was anything more. Just sort of a ‘flex/show your muscles/act tough’ thing. Like one of those wedding pictures they do with the bridesmaids/groomsmen.
Specifically, that is a “Most Muscular” pose.
They’re posing like NFL player Clay Matthews poses after a big play, which is pretty impressive considering he was likely in grade school at the time.
I believe time travel may have been involved.
It’s definitely *NOT *Blue Steel! 
Yeah, flexing like a weight lifter, or a professional wrestler.
They’re all Hans and Franz and they’re there to pump (clap) you up! So don’t be such a girly man or girly girl…
Yes, they were pretty popular SNL characters in their time.
