Actually it does look like it qualifies as a variation of the Hippo Defense, and Blindside and dengmei are wrong. I think it sucks ass too, but if it's been employed by GMs that means you might have to face it as White sometime no matter how much you think it sucks.
Spassky drew Petrosian TWICE in their 1966 WCC playing this crappy looking defense, so he must have thought it was "worth knowing."
Blindside is quite right. Its not worth knowing. Its an uncommon opening. It started as a french defence and redirected to unknown territory.
