In text messaging, "SS" usually stands for "screenshot". It is often used on social media platforms like Snapchat, where screenshotting is a common practice. For example, someone might say "SS this and send it to your friends" to indicate that they want the recipient to take a screenshot of something and share it with others. "SS" can be spelled with all capital letters or with all lowercase letters (ss) . However, it is important to note that "SS" can have other meanings in different contexts. For instance, "SS" is also a term used frequently on TikTok, but its meaning in that context may be different from its meaning in text messaging.
