Sidekoe

Sidekoe is a term used primarily in online communities to denote a secondary online persona, alter ego, or character that a person adopts in addition to their main identity. In practice, a sidekoe may be used for personal storytelling, role‑play, or creative writing, and it often carries its own set of traits, backstory, and social media presence distinct from the user’s primary profile. The concept overlaps with established ideas of an alter ego, OC (original character), or persona used in fan fiction and role‑playing contexts.

The etymology of sidekoe is not documented in major dictionaries or scholarly work. It appears to have arisen informally within digital communities and may be a neologism formed by combining 'side' with a phonetic element such as 'koe,' whose origin is uncertain and likely diverse across communities.

Users may develop a sidekoe to explore different interests, experiment with writing voice, or separate personal and fictional content. Sidekoe profiles are sometimes maintained on separate accounts or within narrative threads, and they may be subject to community guidelines about consent, privacy, and boundaries between real and fictional identities.

Sidekoe remains a niche term with limited academic or linguistic documentation. It is mostly encountered in fan forums, story‑writing communities, and RP sites, rather than in formal linguistic or cultural studies. Related concepts include alter ego, persona, original character, and role‑playing.
