Someone you’ve been friends with for a long time
A “day one” is often a term used to describe a person with whom you’ve shared a long-lasting connection. This connection could be friendly or romantic, but the key aspect is that it’s deep-rooted and has stood the test of time. It’s someone who’s been there since the beginning, through the highs and lows, the good times and the bad.
This term is nothing new but has gained popularity in the last decade or so, around the mid-2010s. It’s a more modern alternative to traditional terms like ‘bestie’ or ‘bae’, used to distinguish the most significant relationships from the rest.
You’re likely to hear or see “day one” being used in conversations or on social media platforms such as Twitter, Instagram, and TikTok. On these platforms, it’s often used in posts expressing gratitude towards a close friend for their unwavering support and companionship, through all life’s ups and downs.
Most commonly, this term is employed by close friends as a synonym for ‘best friend’. It’s a way of showing affection and appreciation. For instance, it could be used by childhood friends who’ve known each other since primary school or a couple who met in their early 20s and have now been married for 50 years.
