Tony Daniel is man of wealth and taste, my friends!
Ironically, within Sir Tony Daniel's response, the term "douchebag" is sexist too. That's a sanitary device that women use for hygiene or medical reasons, correct?
In his slight defense though, while "Friendzone" implies a misogynistic idea, it has a less sexist cousin--the devastation a guy (or a woman) experiences when he (or she) really likes a girl (or boy), but the girl or boy doesn't regard him as dating material.
Sally: Bob, you're really sweet. I love confiding in you about my dates with real men.
Bob: You're the center of my universe. You're my destiny. I can't get you out of my thoughts.
Sally: Do you mind if I torture you for awhile, confiding in you how frustrated I am that the Captain of the University Football Team won't return my phone calls?
And yes, not to be sexist, this can go both ways, with a woman who has an enormous crush on a man, and he declines to see her as anything more than his favorite kid sister.
The difference between this and "Friendzoning", however, is that the "rebuffed courter" is legitimately infatuated with the woman (or man) he/she is courting. The fact that the other party "just wants to be friends" is emotionally devastating.
It sounds like with "Friendzoning", the guy (specifically a guy) was trying to get the girl into bed, and is mildly bummed that she deflected his advances.
