A defecation dost is described as a friend, comrade, or whatever of that sort, who happens to take a shit at the same time as you. The simultaneous ritual of taking a shit while being in contact with each other, ex. Through texting, is when they can be established as this as they are defecating, and being « dosts » (which is friends in the Hindi language).
« Hey dude, I just took the biggest dump this morning my bowels feels RENEWED »
« Same?? Dude I took one too it was ETHEREAL. »
« Oh my god...we’re defecation dosts! »
