Pink Is for Sissies

"A... heart? (I feel my masculinity going... going... gone.)"

—Phoenix Wright on his new badge, Turnabout Storm

The idea in fiction that a male character, when wearing pink, actively manages to lose a great deal of his more masculine qualities, if not outright accused of being gay. This results not just in other people making snarky and rude remarks to him, but may actually result in distinct changes in his character.

Tomboys may also object to this color because it's girlish. As can women who think it's childish.

The trope is the reason Real Men Wear Pink is named so. When women are seen as sissy for wearing pink it also fits into Real Women Never Wear Dresses.

A Sub-Trope of Pink Means Feminine.

Anime

In Kore wa Zombie Desu ka?, main character (and zombie) Ayumu Aikawa accidentally steals Magical Girl Haruna's powers, which allows him to use her powers...and gets turned into a Crossdresser in the process. Made a lot more hilarious in Season 2, where he breaks the magical weapon and is unable to erase people's memories of himself while wearing the magical girl outfit, and then it turns out that that actually made him even more popular, much to his chagrin at trying to live a normal life.

Webcomics

Web Original

In Red vs. Blue, when Donut gets his own colored armor — and it turns out to be pink, however much he insists it's really lightish red — this becomes the impetus for his Flanderization as the series goes on.
In SOTF-TV each character is sorted into a color-coded team. Everyone on the Pink team happens to be male. Naturally, they tend to get a lot of in-universe mocking, and this hasn't gone without a Lampshade Hanging. The best example would be their mentor reminding two members to put their shirts back on, since Pink Team was being called "the gay team".

Mike Patterson: "Oh, uh hello again. I forgot to ask, but um, would one of you boys mind putting on a shirt? People are calling Pink the um, well... 'Gay Team' - err, I mean, not that there's anything wrong with that, um, if you are. Uh yeah, that's all. Take care."

Western Animation

One episode of The Simpsons has Homer freaking out because his work shirts have all turned pink, due to Bart throwing his lucky red cap into the washer while Marge wasn't looking. Marge insists that it won't be a big deal. Cut to the morning grind, where Burns and Doctor Monroe have singled Homer out for "freakish tendencies" and begin plotting for his sanity evaluation.
- Bear in mind that most of the bad things that happen to Homer in this episode are clearly his own fault: Upon being given a take-home psychiatric evaluation, Homer loafs around, trying to get other people to fill it out for him. Eventually, Bart fills out and Homer is predictably thrown into a mental institution when he turns it in without even looking at it.
- Also, Homer's objection wasn't so much to the fact that it was pink, as that it would make him stand out. He said something to the effect of "I'm not popular enough to be different!"
