How do you interpret Snoke's existence?

The way I interpret Snoke is that JJ had a fag packet. On the back of that he probably initially doodled Kylo Ren's mask and went - Yeah, cool! Then, chewing on the end of his pencil, he wrote "Darth Va-- whoops, sorry! Kylo Ren and his mysterious, shadowy leader Palp-- no, let's think - Snoke yes that will do, rule over the Galaxy until a young novice from the sand planet Tatoo-- no, no er Jakku rises to challenge them."

I think that's as fleshed out as Snoke ever was initially.

I'm still angry that we never got told why he was initially a giant but then shrunk back down to normal size 😠
