What is this variation of chess called?

On my chess team we commonly play a chess called "atomic chess" by us but after searching "atomic chess" up on google I found it has much different rules. I am sure wikipedia has it somewhere in there database its just I don't feel like spending 3 hours going through the chess variations page.

The rules are in general similar to regular chess but with one big exception: whenever a piece takes another piece it explodes on contact destroying itself and that piece. Not only that but in the blast radius of one adjacent square around it everything is destroyed. This includes the king so the king can be killed in this game (resulting in them losing.) So a common checkmate against n00bs is 1. e4 d4 2. exd4 Qxd2#. Also the rules of check aren't as strict since the king can be taken and its possible to take the king out it ever being in check (due to the blast radius.) So this results in no games drawn by the king being unable to move since it can but it will be taken. But it does allow the King to move right next to another king resulting in a draw since no where the opposing king moves is safe from the king one step behind it and if it take it just explodes itself. Also if you are in "check" you can just do a move that will take the other player's King since you killed it first and then just won.

Please can anyone help me pin this down. I saw some pretty wild chess variations on wikipedia this has to be on there.
