You've quoted the scene a hundred times. Now perform it.

Dubbed is a group performance game. Someone picks a scene, everyone takes a part, and you dub it — your voices, on cue, over the real picture. A few minutes later you are watching yourselves back and arguing about who ruined it.

Two ways to shoot it

Whole scene. The clip rolls and everybody performs at once, live, talking over each other exactly like the real thing. Your lines light up on the teleprompter as they land.

At your own pace. Everyone works their own lines in their own booth, one at a time, taking as many runs at a line as they want while the rest of the room does the same.

Every line is its own take

Nothing here is one long recording you have to survive end to end. Each line is captured separately, so one fluffed word never costs you the scene. Redo any line as often as you like, nudge a take a few milliseconds earlier or later until it sits properly against the picture, and keep the one that worked.

Then watch it back together

When the room is happy, the dub is mixed and cut and everyone gets a premiere — the whole room watching the finished thing at the same time. Export it afterwards and it is an ordinary video file you can send to whoever needs to see it.

Getting people in

Host a room and read out the five-letter code, or pull friends straight in from Steam. One person can voice several parts, so you can shoot a scene with fewer people than it has characters.

You will need a microphone

That is the whole hardware requirement. Headphones are strongly recommended: on speakers the clip bleeds back into everyone's recording and ends up in the mix twice.
