So i heard if you play 3 Oblivion rings that target each other you can make an infinite little cycle or loop of Oblivion rings that keep exiling each other, the explanation being:

Chaikov: "Of course, casual Magic may be played any way your Pokemon group agrees on..." and "It's not logic. It's Magic!" GainsBanding: "I only play online. The Magic Online shuffler is AWESOME!" Ikegami: "one might think [adult cats] would make excellent tokens. The issue, though, is that they are very hard to exile. They return to the battlefield more often than an undying creature." Astarael7: "Does 121.1 imply that players are supposed to wear their poison counters?" Bimmerbot: "If you move the wrong way and [the poison counters] fall, it's a game rule violation" Helluminatus: "Just remember, if it looks like a duck, smells like a duck, and quacks like a duck, but the oracle text says creature - Bunny , then by god, it's a bunny." MadCow21: "Who are you and what have you done with the real Chaikov?"
How to autocard (do this to specify a card in your posts): Type [c]Black Lotus[/c] to get Black Lotus . Type [c=Black Lotus]The Overpowered One[/c] to get The Overpowered One .
As long as the first O-Ring exiles the only other non-land permanent and it isn't a token, yes, it's an endless loop.
fixed

No it isn't fixed. It if is a token then a second O-Ring would only be able to exile the first O-Ring with nothing returning and the third O-Ring would target the second and release the first targeting the third and loop. If it is a non-token permanent then it would come back when the second o-ring exiles the first and would then be a legal target for either the third or first o-ring.
The other way it would happen is if it is like the LSV video.
This is also explained in the second official ruling for Oblivion Ring :
If there are no nonland permanents on the battlefield other than an Oblivion Ring, and the card it exiled was another Oblivion Ring, casting a third Oblivion Ring will result in an involuntary infinite loop that will end the game in a draw (unless someone chooses to break it by putting another nonland permanent onto the battlefield or destroying one of the Oblivion Rings, for example).
