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.
