What is bump on messenger?

Bump on Messenger was a feature on Facebook Messenger that allowed users to quickly and easily share their contact information with someone they were chatting with. Users could simply tap the Bump button in the chat window and their contact information, such as phone number or email address, would be exchanged with the other person.

Unfortunately, Bump on Messenger was discontinued in 2014 as part of Facebook's efforts to streamline and focus on core features of the Messenger app. The feature was popular among users for its convenience and simplicity in exchanging contact information, but Facebook decided to retire it due to changes in user behavior and the increasing popularity of other messaging apps.

While Bump on Messenger is no longer available, users can still easily share their contact information by manually entering it into a chat window or using other features within the Messenger app.
