Extraction Method 

Previously known as the withdrawal method, approved by the Catholic Church. It needs to be noted that no one ever willing wants to withdraw so it is deemed the extraction method is a much more suitable term.

I'm due my period next week, I had to use the extraction method on him, fingers crossed I am not with child.

The Brown-Hand Extraction Method 

The scientific term for pulling something out of one's ass.

"How did you come up with a thesis so quickly?"
"I simply employed the Brown-Hand Extraction Method."

Efficient Extraction Methods

Techniques designed to maximize the yield of desired resources (water, metals, volatiles) from raw materials (ore, regolith, atmosphere) while minimizing energy input, waste, and environmental footprint. In space, efficiency is survival—every joule of energy and kilogram of mass is precious. Methods include in-situ resource utilization (ISRU) like using solar ovens to bake oxygen out of lunar soil, electrochemical processing of asteroid ore, or passive wind-traps to collect atmospheric moisture on Mars.

Efficient Extraction Methods Example: The MOXIE experiment on the Mars Perseverance rover, which uses electrolysis to efficiently extract breathable oxygen from the carbon dioxide-rich Martian atmosphere, is a prototype Efficient Extraction Method. On the Moon, using concentrated sunlight to thermally reduce ilmenite ore for iron and oxygen is another, as it uses abundant solar energy instead of imported chemicals.
