哥们太铁，同食同寝，在他人看来“基”情四射，这样的朋友就被称为butt buddies。

Butt buddies is a term used to describe very very very close friends of the same sex. Almost as if they were gay but they certainly aren't gay. Often seen together 24/7.

“烟屁股朋友”（butt buddies）用来描述非常非常非常要好的同性朋友。他们好得几乎像是同性恋但事实上又不是。经常没日没夜呆在一起。

例句：

"Dude, I see you and Kevin together all the time; are you guys like butt buddies now?!"

“哥们，我看你和凯文一直黏在一起；你们现在成了好基友啦？“
