看剧时，你喜欢看弹幕吗?近年来，“弹幕文化”在中国越来越流行。打开一部电视剧的“弹幕”，观众的神评论甚至比剧情还要精彩。

“弹幕”，原指向特定方向持续发射大量火炮(the continuous firing of a large number of guns in a particular direction，barrage)，现在用来比喻“观众的实时评论像子弹一样在屏幕上穿梭(real-time comments from viewers flying across the screen like bullets)”，英文可以翻译为“bullet-screen comments”或“bullet screen”。

例句：

一些视频网站上的低俗弹幕十分不利青少年成长，需设立审查机制。

Vulgar bullet screen comments on some video websites is harmful to the development of teenagers and a review mechanism should be set up.
