it was like the vault(which got taken away from us :( ) of the 90s, taken off the shelves because of it being sooooooo bad for you. Brought back and only sold on amazon now but they sold out in a few hours.
I remember not being allowed to drink it. But if I had 35 cents I would get it out of the vending machine. Back then I could get cigarettes out of a vending machine! There was also a high caffeine content cola (say that five times fast) I believe the name was "jolt".
I don't know if it's ever just taste when they reintroduce stuff. For me, it's the nostalgia. To this day, I don't really like Squirt soda, but when I drink one it takes me back to when I was a kid and I'd go golfing with my grandpa. For that reason, I'll occasionally seek it out. Not the best soda, but great memories.
