This is a transitional move that is done to daze an opponent to set up for another move usually. Guys like Shawn Michaels and Triple H were always on the receiving end of it during their matches in their younger years especially. The opponent is on his back, the other guy grabs both legs and fall backwards. Then the person that is on the receiving end somehow has the strength to get back to his feet and end up going into the turnbuckle or over the top rope. There are variations on the move too because sometimes guys won't bump into the corner and will instead jump to the top rope to do something else. For the most part they're going into the top turnbuckle and then selling it like it was some deadly move. It's probably a fun bump to take just because of how it looks and how you can bounce off the ropes as if it is the most painful thing ever, but the setup of the move makes it look too silly even for pro wrestling.
