You are friend zoned when a member of the opposite sex (usually one you want to hook up with) declares you to be "just a friend", thereby ruining all potential chances of sex.

当你想追求的异性宣告你只是他（她）的朋友时，你就此被“划入朋友圈”，你俩之间从此再无可能。

Acquaintance zoned is similar to being friend zoned, only far worse. While being friend zoned can sometimes produce a friend, being acquaintance zoned produces nothing.

“划入熟人圈”比“划入朋友圈”还惨，“划入朋友圈”至少还能做做朋友，“划入熟人圈”连朋友都做不成。
