ladette (also less frequent laddette) /lædet/ noun (BrE, informal)
a young woman who behaves in a confident and noisy way, who drinks alcohol and may enjoy sport or other activities that are traditionally enjoyed by men.
Analysts believe the ladette phenomenon has been driven by increasing levels of financial independence among young women.
17-year-old Zola and her gang of ladettes boast about just how much under-age drinking they did last weekend.
She has also had a reputation as a hard-drinking, hard-partying ladette who seems to enjoy the single life.
