Crab juice from some spot out of York, PA.
A buddy of mine (from York) picked some up for me to try and it's terrible, as others have said for years. Completely ruins any wick, tank, etc. upon touching it. As an aside, I let another friend try it before tossing the tank and he probably took a good eight or nine drags before deciding, "It's not for me." Yuck!
Edited to add - Crab juice tastes like someone farted into a glass of salt water...and then you vaped it.
We've got a winner!
