... Wait, reading the flowchart - what's the issue with using the term "friendzone"? Am I using it wrongly? Why must I use it ironically?
For example, if I flirt with someone for a whole night, and she ends up telling me that she's not interested and wants to be friends, how am I not friendzoned?
Do I no good English speak ?
The whole term implies that she willingfully turned you down, despite the fact that she would be attracted to you.
Which is BS (for 99% of all cases, probably; let's not generalize to broad).
In your example you just had no chance at all, because she was not attracted. Period. It's not so that she just let a chance vanish, but rather that there was never a chance.
