狗屁在英语中通常被称为"bullshit"，意思是废话、胡说八道或欺骗。这个词的来源可能与狗的排泄物有关，因为在古代，狗的排泄物被认为是无用的、没有价值的东西。

例句：

I don't believe a word of what he's saying. It's all bullshit.

（我不相信他说的一句话，这都是狗屁。）

Don't try to feed me that bullshit about not having enough time.

（别把那个没有足够时间的狗屁给我吃。）

She's just trying to sell you a bunch of bullshit. Don't believe anything she says.

（她只是想给你卖一堆狗屁。不要相信她说的任何话。）
