1) In my area, a poptart is a word to describe those who are bent on the new culture of music, Pop being the leading, closely followed by any R&B or Hip Hop artists. As in they only listen to their type of music and bash any other type of music they listen to. They tend to have no reguard for other types of music, and continue their violent rampage on making 'their' type of music the 'number one'.

2) A tasty snack that can be eatten in the morning.
1) Person number one: Hey! Have you checked out that System of a Down CD?
Poptart: No way! OMG! That music is like, so stupid! I only like MY music. Like Brittney Spears, and HILARY DUFF, and BLACK EYED PEAS! OMG!~ MY HUMPS!!!121!

2) Person number one: I ate poptarts this morning!
Person number two: No fair! I just had that nasty poisoned school lunch.
