Why are you so skilled at braiding? How many times have you done it?
Parody of galgame White Album 2 line, which is now a popular meme in Chinese net-society.
Supporter of one of the two main heroine Touma Kazusa usually accuse the other heroine Ogisa Setsuna for being a bitch, and supporter of Ogisa usually accuse Touma for having an affair with the male protagonist, and argument like this usually evolve into some kind of war of word. Thus, parodying this White Album 2 line is seen as an act of (comically) igniting a fight.Keep saying that and I will beat the crap out of you....
Also a part of the White Album 2 meme.
If someone parodies any White Album 2 line in order to start a fight of some kind, simply beat the shit outta him so no one else gets hurt and effectively stops the fight. Looks like yuri of two closely related girls, but is actually an intercourse between two guys in their 30s
