I was wondering why that move looked so familiar ... (GOT7)

So GOT7 seems to be all the hype right now. OwO

And I watched their video when they came out (had really high expectations for them since predebut, but I didn't find their song to be all that great ^^; good, but not great. )

And, as the weird person I am, I look through old and rather unknown kpop groups. And I was tyring to update the info on some of my lists, when I got to the "M" groups. Mr.Slam is a group that I hardly payed attention to, but as I was sliding through their things, I came across something that reminded me of GOT7. A certain flip dance move that Mr.Slam's Yongjin does is similar to the one we've seen GOT7's Mark do various times predebut and now. 

Mr.Slam is a group that debuted in 2012. After awhile they became inactive and disappeared, although they never officially disbanded, to their fans its more than a fact that they are no longer when one member (Yongjin) debuted in another group in the summer of 2013.

Now before anyone even tries to get all touchy about me "claiming that GOT7 copied Mr.Slam". No. I'm just saying the dance move was similar. In fact that dance move does not belong to GOT7 or Mr.Slam, its just a dance move we don't see often in KPOP groups.
And I wanted to share the similarity of the move between the two groups.
