You can’t say “one popcorn” or “two popcorn” because mass nouns aren’t countable. It’s just “popcorn” for any amount of popcorn. Notice I said “amount” and not “number” because, again, popcorn is a mass noun and cannot be enumerated. If you want to enumerate kernals of popcorn, you have to say “kernels of popcorn”.

Yes, you can. I just did. Try to stop me.
