I'm just wondering what does the word "ぶつまね" (or also ぶつ真似 as turned up by a google search) mean? I tried guessing from the context of some 10 example sentences but still can't come up with the meaning of the word.
My original sentence is this one:
「先輩っ。ひっかけ問題はひどいです」ぶつまねをするテトラちゃん。
The girl in question is tricked into answering "yes" to a question of whether a given calculation is correct. The answer she had been given is almost right except for a single number in it.
Thank you in advance.
