A beautiful girl who makes everyone smile. A Maryelba can sometimes come across as sassy. Maryelbas never mean any harm though, they just like to have fun.
A snooty, proper, entitled person, who attempts to gain control in interpersonal interaction, through feigning superiority, condescending to others as a general rule, and attempts to flaunt a status she does not, in fact, hold.
She's such a MaryElaine- she'll find a way tolook down her nose at someone and bully them, even as she picks her butt.
