OTP
In fandom, OTP means "one true pairing," a person's favorite romantic couple, usually fictional.
By Cal Hewitt, Gen X · ·
What it means
An OTP is the pairing a fan roots for most strongly. It often refers to fictional characters, including a couple the fan imagines rather than one made canon by the source material. The term can be used lightly, and people can have more than one pairing despite the word "one." In security or login contexts, OTP instead means one-time password, so the fandom setting matters.
See the quick definition in the OTP dictionary entry.
How to use it
“Nick and Charlie are my OTP.”
Naming a favorite fictional relationship.
“The show never made them canon, but they are still my OTP.”
Supporting a fan-created or non-canon ship.
“My OTP changes depending on which season I just watched.”
Using the term casually rather than literally.
Where it came from
OTP arose in online fandom and shipping culture; no individual inventor or exact first use is documented. Merriam-Webster describes it as a fandom term for a fan-created coupling, and Dictionary.com identifies the full form as "One True Pairing." Its origin is online fandom, with the exact date and coiner unknown.
No single person is credited, the origin is disputed.
Where it's popular
English-language fan-fiction, fan-art, and social fandom communities, especially spaces where people discuss ships. The evidence supports a community origin, not a reliable country-level origin claim.
Use is common across multiple fandoms and platforms, including discussion forums and social media.
How it caught on
- before 2010sOTP circulates in online fandom and shipping culture, but a reliable single first use is not established.
- 2015MTV uses OTP in coverage of Stephenie Meyer's gender-swapped Twilight retelling, a documented mainstream-media example cited by Merriam-Webster.
- 2018Dictionary.com publishes an acronym entry defining OTP as "One True Pairing."
- 2019A Vox essay about shipping uses the plural "OTPs," illustrating that fans often use the term flexibly despite "one" in the expansion.
Common mix-ups
OTP does not mean every fan agrees that a couple is objectively destined to be together. It names a personal favorite. It also has a separate technical meaning, "one-time password," outside fandom.
