'Everyone in the chair has their thing.' So what would be your thing?

I would like the ship to go. Now.

alright alright alright.

At your pleasure

Either "lets fucking gooooooo" roared at full volume.

Or "do the thing" in a barely audible mumble.

And crew would never know which to expect.

"Let's do it."

[Specific command containing speed and heading], [helmsman's name]

This businesss with a catchphrase is too corny and meta. Keep it simple and direct, like Kirk did: "Ahead warp factor 8, Mister Sulu."

I'd start singing 🎶 on the road again

Release the Treken!

Seems like Starfleet would have a selection of 5 allowable "Engage" variations lol so that everyone get's trained on how to know when to go

Who the fuck put me here aaaaaaaaaaaah

Disregarding that: "Reingehauen!" (I specifically requested this not be translated)

"Okay, 3, 2, 1, let's jam" or if we're in a hurry "SHOWTIME"

"Let's go."

Although I'm also partial to Saru's "Proceed." or French-Dub-Picard's "Energise".

"Let's make like a tree, and get the fuck out of here!"

On a ship capable of traveling the mycelial network like on DSC, "Make it spin!" Because I would be familiar with Stargate SG-1 in Star Trek. When IPs collide, a nebula spawns a star.

Otherwise, "Let's go!"
