Synching 

Popularized by The youth of Los Angeles, Synching is the gesture of "Synching" energies with another person by facing your palms to one another and making small circular motions. Its been known to be the new handshake as it can be done at a distance, does not require physical contact, and can be done with multiple people.

Synching is most commonly performed when two or more people find themselves agreeing on a particular subject, during moments of excitement, or as greetings/farewells. That way, it shares the positive energy that the two people are feeling in that moment.

Will: "Do you like that show, Workaholics?"

Dorothy: "OH MY GOD YES!! I Love that show!!"

Will: "Me too!!"

(Will and Dorothy sync upon learning they both feel the same way about a certain subject)

rip syncing 

Similar to, but different from, lip syncing as rip syncing is the act of actually singing words, typically at the top of one's lungs when very drunk and having little care for the actual lyrics.

Jim was hammered last night and got rip syncing with Jill the entire Boston album. Between the two of them, they knew about 40% of the lyrics and 100% of the choruses, which the yelled very loudly.

Syncing slower than the titanic 

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!
