Plenty to choose from. Hanae from Kyou wa Kaisha Yasumimasu and Sakura from Last Cinderella, to start things off. The former is stupid, the latter is disgusting. Also, any character played by Hirosue Ryoko; all the hysterical mothers (and in-laws) whose sole purpose in life is to make people miserable; Mei from Love Shuffle; Ha Woo-jin from k-Liar Game (you’ll never be Akiyama!), the entire cast of Trainwreck Cantabile, and so on and so forth.
