I invented this word, I think, because I had read somewhere of the word "enfreight". To defreight means to extricate many bodies from a small area after having moved many miles. The idea of living mass as freight can be understood only when 8 to 10 people in a car travel great distances.
"Upon our arrival in Toronto, the defreighting process had not gone smoothly; we had literally slid out of our Chevy"
