Although the exact original recording behind this clip is not clearly documented in the soundboard listing, the phrase since day one has long been used online as shorthand for loyalty from the start. On TikTok it fits the platform's tribute and friendship edit format, where a short audio can carry an entire montage without needing explanation. That simplicity helps it travel: creators reuse the same line for friends, partners, teams and pets, and viewers instantly understand the message even without context. Its staying power comes from that broad, sincere meaning rather than a single viral moment.
About this sound
A short TikTok trend audio built around the phrase since day one, used in loyalty and friendship edits to mark someone who has been there from the start.
The clip is a short TikTok audio built around the phrase since day one, used to celebrate a person, friendship or team that has stayed loyal from the very beginning. It plays for just over sixteen seconds, long enough to sit under a photo montage, a before-and-after sequence or a slow reveal without taking over the edit. The tone is warm and affirming rather than funny or dramatic, so it lands as a sincere tribute. Viewers tend to read it as a thank-you, a reminder of shared history and a quiet statement that the bond has not changed.
