手机响了，接起来却只听到嘈杂的声音或是隐约听到有人在说话或唱歌，你“喂！”了几声可就是没人跟你说话。你以为是信号不好就回拨过去，结果对方很无辜地说：“我没有给你打过电话啊。”于是，你才意识到原来之前那个电话是butt call。

Butt call refers to an unintended phone call placed by sitting on one's cell phone. Maybe the phone bumped up against something in a purse or briefcase, or rubbed up against a seat belt. Or maybe the phone fell on the floor. Maybe the person just sat on their phone—which explains why some industry insiders call inadvertent dialing "butt calls."

Butt call（误拨电话）指误坐在手机上而拨出的电话。有时候可能是手机放在钱包或公文包里碰到了什么东西，或者碰到安全带了。也或许是手机掉到地板上了。甚至可能是有人坐在手机上了——这也正是业内人士把“误拨电话”称为butt call的原因。

A variation on this theme is the pocket call, an unintended phone call placed by accidentally pressing the buttons of a cell phone in one's shirt or coat pocket.

跟butt call相似的另一个说法是pocket call，即手机放在衣服口袋里不小心碰到通话键而拨出的电话。
