AMOS is an acronym that stands for "Add Me On Snapchat". It is commonly used on social media platforms like TikTok, Instagram, and Twitter as an invitation or request for other users to add the person on Snapchat. Many people, especially influencers, place it in their bios on other social platforms to encourage people to contact them via a different platform. Some people use it in their online messages, like when DMing on Tinder or when texting with a new friend or connecting through different social channels. There is also an app called Amos that is a friends finder community for young people to meet new friends with the same interests, post photos and videos, send instant messages, and more.
