參加活動認識了很多新朋友，對其中的一兩位還有興趣多了解一下，于是，就主動搭訕了幾句。結(jié)果，人家被這熱情嚇到，立馬順口提及自己的男朋友/女朋友，暗示你不要再靠近。

Boyfriend/girlfriend drop refers to the act of subtly adding the fact that you have a boyfriend/girlfriend into the conversation in order to deter anyone who is potentially interested in you.
“扔男友/女友”指在聊天的時候不經(jīng)意提起自己有男朋友或女朋友的事情，目的是為了擊退某個對你感興趣的人。

For example:

She thought I was interested in her and boyfriend dropped me in our last meeting.
她以為我對她有興趣，于是在上次見面的時候就告訴我她有男朋友了。

這個說法大概是來自于英語中另外一個使用較廣的表達name drop，名詞形式為name dropping，也就是我們平時說的“拽人名”。

Name dropping is the practice of mentioning important people or institutions within a conversation, story, song, online identity, or other communication.
Name dropping指在談話、故事、歌曲、網(wǎng)絡(luò)身份或者其它交流中提及重要人物或機構(gòu)的行為，即“拽人名”。

Name dropping is used to position oneself within a social hierarchy. It is often used to create a sense of superiority by raising one's status. By implying (or directly asserting) a connection to people of high status, the name-dropper hopes to raise his or her own social status to a level closer to that of those whose names he or she has dropped, and thus elevate himself or herself above, or into, present company.
“拽人名”通常是為了在某個社會層級中確立自己的地位，通過提高自己的地位來建立一種優(yōu)越感。這些人在暗示（或者直接表明）自己與高層人士的關(guān)系時希望能夠?qū)⒆约旱纳鐣匚惶嵘脚c那些高層接近的狀態(tài)，從而凌駕于身邊同伴之上，或者成為與其平等的一員。
