It's a form of auto-erotic asphyxiation by using gravity.

Basically, you jack off normally; but before you nut, you squat down as low as you can to the ground and breathe short shallow breaths while still whacking it. This part is called "Getting in the shuttle."

As you nut, you jump up from that squatting position as fast as you possibly fucking can and hold your breath. This is considered "Take off."

If performed correctly, you should become VERY lightheaded and experience pure bliss due to the orgasm from your cock rocket. This is called "Being in space" due to the fact you feel like you're floating.

This is a technique that should be performed only by professionals, in a controlled environment.
Dude I tried to perform the Major Tom Technique but when I "Took off" I fucking jumped up at Mach 50 and must've ripped a fucking hole in the goddamn space-time continuum. Because the next thing I know I was laying on the ground with my dick out, covered in space juices from my trip around the sun.

A fictional astronaut in David Bowie's lyrics. Also, as a metaphor: altered state of consciousness (with or without drugs), people in such state, who lose a sense of reality (have no ground control).
My mama said to get things done you'd better not mess with Major Tom (Ashes to Ashes by D.Bowie).

It is a way to masterbate where you jack off normally, but before you nut, you squat down as low as you can to the ground and breathe short shallow breaths while still whacking it. This part is called "Getting in the shuttle."

As you nut, you jump up from that squatting position as fast as you possibly fucking can and hold your breath. This is considered "Take off."

If performed correctly, you should become VERY lightheaded and experience pure bliss due to the orgasm from your cock rocket. This is called "Being in space" due to the fact you feel like you're floating.

This is a technique that should be performed only by professionals, in a controlled environment. By hyperventilating and jumping up, you are literally cutting your brain off from oxygen. No oxygen = no consciousness.

After passing out you come crashing down with a thunderous boom. This is called "Reentry"

It is at this point where your mother walks in to see you laying there covered in your "Star Dust". Be sure to glare at her with the confidence of Buzz Aldrin. She will then stomp out of the room without saying a word. This part is called "Disappointing your mother."

I performed a Major Tom last night. I still have not left my room. I don't know what to say to my mom.

A person who cannot hear you, no matter how many times you repeat their name. The term is derived from the song Space Oddity.
Person 1: "Can you hear me Major Tom?"
Person 2: "Yes, I can hear you!"

A masturbation technique where you squat before you finish and start hyperventilating. As you finish jump up like a rocket and breath out. This will cause you to enter a transcendental state where you feel like you are floating in space as you orgasm. If one will attempt this, ensure there is a soft place to land on.
My friend tried the Major Tom, and he says he will never be able to orgasm normally again.

An auto-erotic asphyxiation technique using only gravity.
It is performed in three steps:
1) Getting in the Shuttle: Masturbate till you are close to orgasm and then squat down while taking short shallow breaths.
2) Takeoff: As you orgasm, hold your breath and jump up as fast as you can.
3) Being in Space:If performed correctly, you should become VERY lightheaded and experience pure bliss due to the orgasm from your cock rocket.
