-being "friendzoned" does not have to mean something negative in nature, it is simply a word to label the common situation of a male is only seen as a friend in the eyes of a female come the time he confesses his feels for her, which is completely ok, by no means does the male friend feel he is intitled to be with said female(unless they are an assholes), everyone obviously has the right to reject who they wish, but that does not mean the male has no right to feel rejected and inadequate, especially in situations where said female chooses to be with another man of which the male friend feels is not appropriate for said female, for whatever reason, such as opposing males personality(taking advantage of her and such). its mostly based on social norms and essentially stereotypes of male and female interaction. Of course this is not always the case, it is possible for a female to become "friendzoned" as the roles are simply reversed, though it is less common as guys are more in the position of asking a girl to be with him (a social norm). I personally dislike like the reality of social norms, but that does not mean they are not blatantly obvious, more so when observing rather than participating.
John had a chance when they first met but he messed it up by not doing anything about it. When he finally got his act together, the friendship that developed actively interfered with his potential of getting Mary to go on a date with him.
Girl: I don't like you like that let's just be friends.
Boy: she wants to be friends.
Friends: She just friend zoned you
Guy: Yea, I get it, I'm in the friend zone.
Girl 2: I just want to be friends. I'm not looking for a relationship now.
Guy 2: Translation: you want someone else.
Girl 2: Correct.
