“Been There, Done That” (#BTDT) is a phrase and hashtag used on social media to express that someone has already experienced or tried something.

In influencer marketing, #BTDT is often used to share experiences or signal that a certain product, trend, or activity is nothing new. Depending on the context, it can come across as confident, experienced, ironic, or even slightly dismissive.

For influencers, #BTDT can highlight expertise or familiarity, while also being used humorously to comment on repetitive trends or common social media situations.
