Lovers Tag

This is a sweet way to say one person is tagging another as their main love, like putting a label on a gift with a heart on it

It could be used in a group chat to show that two people in the chat are officially a couple, with the tag as proof

On social media, this might show someone is marking another as their partner, making it clear to others who is taken

At work, someone could use it to tag their favorite coworker as their 'office sweetheart', just for fun without being serious

For friends teasing each other, it might be used to say one person is another's 'official favorite' in a joking, affectionate way
