Clique-stalking is the act of surreptitiously investigating a person’s friends or social media connections.
Clique-stalking指偷偷調查某人的朋友或社交媒體人脈的行為。

Clique-stalking happens when you fall down the rabbit hole of clicking the names tagged in distant friends’ photos, then cross-checking for other mutual friends; when you Google a stranger because you always see her commenting on your ex-boyfriend’s friends’ Instagrams; when you see a Twitter handle you don’t recognize in an @-reply, then check who else he’s been talking to.
如果你沉迷于點擊遠方的朋友的照片里標記的人名，然后反復核對你們是否有其他共同好友；如果你因為看到一個陌生女性總是點評你前男友的朋友的Instagram照片，就開始用谷歌搜索這個陌生人；如果你看到@自己的回復中出現不認識的推特賬號，就會查看他還在跟誰交流，你就正在Clique-stalking。
