The "friendzone" is the position of a person who removed from eligibility for romantic or sexual
consideration due to an existing friendship with the object of their desire.
The term applies to a range of situations: On the innocent end of
the spectrum, awkwardness, timing, or fear of losing the friendship may keep a person in the friendzone.
There those who step forwards to confess, to be rejected and told remaining friends is more desirable. They must either enter the friendzone, or end all contact. Or, the focus of the desire may be aware of the romantic interest, and purposefully ignore, discourage, and downplay it to prevent the friendship from changing.
At the pernicious end, either person in the dynamic may use the friendzone to take advantage. A person with sexual interest may try to use the friendzone to gain intimate access under the guise of false friendship. Or the recipient of affection may purposefully encourage the feelings in order to get benefits, like attention, favors, or money (aka "simping")
It is
challenging to shift a person's view from platonic to romantic, so becoming "trapped in the friendzone" is seen as a difficult fate to change and few successfully "escape the friendzone" to enter a
relationship.
The term can be parodied in other situations where a person is rendered romantically inviable due to the type of existing
relationship, such as "brother/sister-zoned" (i.e. the object of the feelings views the other person like a sibling)
