The phrase “there’s no such thing as straight people mario” is a popular internet meme that originated on the social media platform Tumblr in 2014. The phrase is often used to express the idea that heterosexuality is not a natural or essential part of human identity, and that it is a social construct that is enforced through cultural norms and expectations.
The phrase has been used by LGBTQ+ activists and allies to challenge the idea that heterosexuality is the only “normal” or “natural” sexual orientation. It has also been used to critique the ways in which heterosexuality is often privileged over other sexual orientations in society.
