It's definitely "pop". People from the Northeast look at you funny if you say "pop" but I don't care.
How about Pop Rocks? Do they still make those.
What a great candy for a kid..
Candy that makes me say WTF but also

:
Pixie Sticks - Hey, come get a little bag of sugar you rambunctious little s#!ts!
Fun Dip - Hey, you little bastards want to soak up that sugar with a sugar stick!?
Candy Cigaretter - WTF? How about Wonka brand heroin dime bags
Beef Jerkey Skoal - See above (not really candy though)
