One of the many attempts to create an N-word like term to describe white people. Essentially, whenever a white person is acting ignorant or foolish, or simply too white, one may call them a poptart.
Damn, theres more poptarts in here than a fucking kellogs factory!
Imma throw you in the toaster poptart!
Shut up you property-owning, money-having, child-rearing, cracker-ass poptart!

basically this is anyone who is considered a space case, twink, or ditz. It is usually referring to girls but it can apply to guys as well. the person must be in high school and must be considered to be one of the "popular" group. this is what the "pop" in poptart refers to. the "tart" part of it is easy: fake, slightly stupid, and annoying. Tart is an old insult so it makes sense here.
That girl is such a PopTart. Why dosn't she ever think for herself?

used to describe those who are under the influence of extreme ditzyness and/or insane insucurities that cause them to act exactly like everyone els in the poptart population!! Often found gossiping about everyone(even their own kind)flirting or playing hard to get with every male that has a pulse, or making fun of random individuals just because they're different. Poptarts are usualy described as bitches or glowing angels.
WARNING: if one of the poptarts ever askes you to join they're 'group' be prepared to be sucked in, become beutiful but also a backstaping bitch, and drop about 50 pionts off your IQ.
Billy: Fuck, did you hear those poptarts yesterday gossiping about Amanda?
