↘666↙

↘666↙ is orally pronounced the same as "陡陡陡陡", and these four characters together mean: "Cool Cool Cool!" Like the highest measure of approval of your action, recognition of you as a cool and lucky son of a ♥♥♥♥♥.
Writing three sixes is of course easier than writing four characters 陡陡陡陡, so that’s what Sagamon did.
So if Sagamon sends you a "666!" message, don't be alarmed - he just thinks you're a cool dude and not a minion of the devil.
