This trope doesn't come from nowhere. Still some sisters are so choleric and needlessly angry, they can be seen as mean. Lynn, Lola and Lori have serious anger issues. Lisa is mean becuase she experiments on her family without permission, she harvests organs and causes more damage than heal. Lana is mischievious to Lola, she was destroying her dolls in Along came a Sister and Room with a Feud. Luna took level in jerk in season 2. Luan becomes were-Joker at April Fools. Lincoln is often a jerk because he manipulates and uses his sisters for own selfish benefits, the worst of him was in infamous making the case. Leni is known from being the nicest because she's too stupid to care only about herself, Lily as a baby innocent in 99%.
