Meme Seku is the name of the kid in the lame-ass movie Jungle 2 Jungle. Apparently, it means "cat piss." The kid picked this name because he lives in some tribe in South America.
Note that the real name is spelled, according to IMDB, "Mimi-Siku," but the original spelling remains intact because that's the way Adam and Liam thought it should be spelled.
