Well, for one it could be Khora's skill summoning Venari. Or it could be Sevagoth's Reap skill. Or it could be Wukong's hold version of the clone attack...it could be a whole lot, actually.

Looks more like a reference to the iconic pose of Jotarou summoning Star Platinum

I believe it's specifically referencing Eleanor's scene towards the end of The Hex quest, in Warframe 1999. However, I feel like the Warframe scene itself may be a reference to the Jojo scene, as noted by @Myhel (Especially considering Rebecca Ford, the creative director of Warframe, is a huge Jojo fan herself.)
