"I'd say there was a subtle subtext here that Sam is deeply in love with Frodo, but it's more like skywriting with brass band accompaniment."
Homoeroticism, yay!
Those moments of plot, dialogue, acting, etc., that fans delight in interpreting as homoerotic.
It probably originates from the old days, when the homosexuality taboo was serious enough that every gay pairing was considered a
Crack Pairing, so when authors wrote characters as very intimate with each other, everyone just accepted that they are just very good friends, and moved on, or when they wrote outright references to homosexuality, everyone just laughed at the sheer absurdity of the thought, and moved on.
With the emergence of
Yaoi Fans and
Yuri Fans, and the more open-minded writers, this changed forever. Nowadays, fans willingly interpret any interaction as potentially gay, even for characters without canon orientations and even for those specifically
stated by their creators to be straight.
In the related trope called
Foe Yay, even
rivals or
mortal enemies can get this treatment by fans and writers alike, especially if they have
a more friendly past together, or one is
inordinately obsessed with the other. In
Fan Fic, this is the direct cause of many a
Slash Fic.
This list does not include genuine
ship teases or scenes of objective
Homoerotic Subtext between straight characters.
