Short for d'ebutante, a term for the subject of a coming of age event in which a young girl "makes her debut into society." Often in a very formal context. Can be defined by the trained edge at which they interact with others and portray themselves.
In this shorter version it can be:
1] n. A sassy remark on the noticable effort another puts into their appearance/presentation.
2] adj. The act of preparing for a big entrance.
3] n. A word that an actual debutante would use if they were feeling rebellious.
1] Honey, stop being such a deb before I rip your fake eyelashes out.
2] Deb me up.
3] The debs and I are going to sneak in a couple of 40s to the country club tonight.
