Space Flag 

When a man and a woman are having sex in a bed and the man lays on his back, his penis erect, and the woman jumps into the air off the mattress and tries to aim her self in such a way that her vagina lands over the man's penis (his penis entering her vagina) leaving him unharmed.

Guy 1: Mary tried to perform the "space flag" on me last night.
Guy 2: Did you let her? Did it work?
Guy 1: I think my dick is broken. I think I need medical attention.

spacelag 

Reduced muscular co-ordination, diminished mental faculties leading to extra long reaction time taken by someone who is stoned.

Its like jetlag except here your coming back from outer space.

It took Jack 20 minutes to open the can of cola - he is soooo spacelagged.

Spaceflight Simulator 

A game that teaches you how you can make rockets and learn rocket science, A simple game can make you a Nasa Astrologist.

Person A: Do you know Spaceflight Simulator?
Person B: Yes of course! Spaceflight Simulator is fire!!
Person A: Same I play it!

Spaceflight Sciences

The multidisciplinary field dedicated to figuring out how to leave the planet without exploding, burning up, suffocating, or any combination of the above. It combines physics (thrust, trajectory), chemistry (fuel that doesn't blow up too soon), biology (keeping humans alive in a metal can), and psychology (keeping those humans from murdering each other in said can). Spaceflight sciences have mastered the art of launching multi-billion-dollar equipment into the void, where it either works perfectly or becomes very expensive space junk. The field's greatest achievement is making the impossible merely extremely difficult.

Example: "He studied spaceflight sciences for eight years to learn how to calculate orbital insertion burns. He now works at a company that launches satellites and spends most of his time explaining to management why launches get delayed due to 'weather,' which is spaceflight-scientist for 'something's wrong and we need to pretend it's nature's fault.'"

Spaceflight Technologies

The incredible machines and systems that make space travel possible, from the rockets that defy gravity (barely) to the life support systems that keep astronauts alive (fingers crossed) to the spacesuits that are essentially personalized spacecraft (with limited mobility and an unfortunate diaper situation). Spaceflight technologies include heat shields that laugh at re-entry temperatures, navigation systems that find a specific spot in the vast emptiness, and communication arrays that send messages across millions of miles with the latency of a really bad Zoom call.

Example: "He bought surplus spaceflight technologies from a government auction—a actual flight-tested heat shield panel. He hung it on his wall as art. Visitors asked if it had been to space. He said yes, and also that it had survived temperatures hotter than the surface of the sun, which was more than could be said for his last relationship."

Spaceflight Engineering

The practice of designing, building, and testing the vehicles that carry humans and cargo beyond Earth's atmosphere, requiring a tolerance for risk that would be considered pathological in any other field. Spaceflight engineers must account for vacuum, radiation, extreme temperatures, and the fundamental hostility of the universe to human existence. They work with margins so thin that a single faulty O-ring can end a mission and lives. They then watch their creations launch, knowing that if they made a mistake, it will be very public and very final.

Spaceflight Engineering Example: "She was a spaceflight engineer who spent three years designing a valve for a rocket's fuel system. The valve worked perfectly during tests. On launch day, she watched from mission control, holding her breath for the two minutes the valve was active. It worked. She exhaled. Then she started worrying about the next valve, because that's what spaceflight engineers do—worry sequentially."

Spaceflight Social Sciences

The study of how human societies organize, fund, and react to space exploration, from the Cold War space race (we'll go to the moon because they're going to the moon) to the modern era of private spaceflight (billionaires racing to see who can build the coolest rocket). It examines why nations spend billions on space when problems exist on Earth (prestige, mostly, plus the off chance of finding aliens), how space agencies manage public perception (carefully staged photos, heroic narratives), and what happens to astronaut marriages (usually divorce, space is not kind to relationships).

Spaceflight Social Sciences Example: "A spaceflight social sciences study examined why public interest in space spikes during launches and crashes during the years of preparation in between. The conclusion: humans have short attention spans and space is mostly waiting. The study recommended more explosions, as those get views. NASA declined to comment but did schedule more test flights."
