A Bimbette is a younger version of a Bimbo...usually a young teenager in middle school or a freshman in high school.
Geezz look at that Bimbette dancing over there! What get's me is... there is no music playing! Ohmigosh! I'm so stupid...I thought at least one out of the five guys laps I sat on would like me! I feel like, like, such a Bimbette! Ohmigosh! Where is my lipgloss? Oh! I better text someone before they forget about me!
