Technology/computing-based pun: it took nearly 3 hours for the Titanic to sink on April 14th 1912 so the pun can be used when files take longer than expected to sync.

Sync is the homophone of sink.

Sync being the abbreviation for synchronization or the process of keeping dataset copies consistant between one another in a computer system/network.

Sink meaning for something to go below the surface of water.
Jacob: Wow it's taking 3 hours for my files to sync with the network when it should have only taken 1 hour!
Jillian: Well you can say it's syncing slower than the titanic.
Jacob: Ah nice computer geek pun there!

When you accidentally synchronize a video to the audio in a montage, edit or fragtage in a game.
For a good gaming edit you need a good song to time the shots with the songs... but sometimes a miracle happens and when you add the song the video is like made for the edit... it's PERFECTLY timed to the shots and only happens to experienced editors maybe once or twice in a lifetime... It's truly magical to see!
I JUST ADDED A SONG TO MY COD EDIT AND A MIRACLE SYNC HAPPENED!
