Hmm... or you could just give the wildest laugh you can imagine, loudly nevermind... Then suddenly, wisper into his ear, "Ni ge wo xiao xin yi dian..." or "Xiao xin guo ma lu... bu yao ge cher zuang..." Then laugh wildly again and calmly walk away... Then just before leaving the room, turn and smile at him again, then walk away, with your laughter echoing down the hallway... "cold air blows"
Or you can also do like what the mother in "Beautiful things"did... "Gan ni na be! Chao chee bye ar ni! Aiyo!!! Ni zhe ge wu ya zui ah! Me you fu mu sen de ah?! Bou ga xi! Ni ta ma de ce(how totype eat???) yu yan gen shi har! Lao sai ge sai yan shi! Shen ni er zuo ji! Sen er zi tong xin lian!!! Ni zhe ge BIAN TAI!!!! GAN NI NAH! Lao niang de xin qing to mei you le lah!!! Ta mah de CHEE BYE KIA!!!
