Unlike famous internet slang such as LOL, BRB, or IMO, STTM never became a mainstream abbreviation. Instead, it appeared in smaller online communities, instant messaging platforms, gaming chats, and personal texting.

Today, it occasionally appears in:
- Private text messages
- WhatsApp chats
- Discord servers
- Gaming conversations
- Social media comments
Its popularity depends largely on personal friend groups rather than internet-wide usage.
