Very high-quality cocaine, usually right off the key and uncut. Doesn't look like regular coke---it's flaky instead of grainy, it's sparkly instead of dull, and it's slightly yellow-grey instead of being plain white. Good shit, since 1 gram = ~12 lines. Numbs all the way down and gives you a case of the chills.

A term popularised by Kaish, derived for slang terminology for high quality cocaine and subsequently assimilated to be descriptive of anything of high quality or good.

Cocaine straight off the key(kilo)doesnt have a shine when in the key but when broke has shiny layers on each lump looking like a shiny pearly flake bit like if u opened a can of tuna flakes and broke those layers apart each layer would have a shiny pearly coating to it just like fischscale coke
