From many hours of playing as captain in PULSAR: The Lost Colony, it's usually one of: "Whenever you're ready", "Can we please just go now", or "Fine, I'll do it myself".
I've decided that to combat people on the Threadiverse just assuming everyone else is from the US, like we had with Reddit, I'll be talking how I normally talk here.
So my thing would be "howay!" (pronounced like a fast "howie") or possibly "gan on, then!"
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.
