It's the name for this Miiverse revival. Just a speculation, but it is likely in reference to the way this program acts; it juxtaposes (goes over/rewrites if you will) over the initial Miiverse supported by the Nintendo Network that is unusable, and uses Pretendo Network instead.

oohhhhhh ok, i was getting confused, super late to the party here on my side, seeing the name go around and everyone saying juxt lore, wasnt sure if anything was going down lol

dw its all good
