Trilulilu was the biggest user-generated content (UGC) website in Romania on which users could view, upload and share videos, images and audio files.

The website was created on January 22, 2007, after a few weeks of beta testing, by two Romanian entrepreneurs Sergiu Biriş and Andrei Dunca.

Images and videos that were considered to contain potentially offensive content were available only to registered users over the age of 18.

The uploading of pictures and videos containing defamation, pornography, copyright violations, and material encouraging criminal conduct was prohibited by Trilulilu's terms of service.
