two people who split a room, an egg, and zero privacy from day one
means two offspring produced in the same pregnancy, or by extension two people or things that closely resemble each other
from From Old English "twinn," meaning "double" or "two-fold," itself rooted in the Proto-Germanic "twīhnaz," a cousin of words like "twain" and "twice" and ultimately tied to the ancient root for "two" ("dwo-") that fans out across Indo-European languages — the same root hiding inside "double," "duo," and "duet."
