the.com/twosome

A couple doing something a crowd pretends is intimate, like golf.

means A pair of people doing something together — often with the implication that two is a cozy, exclusive number.

from Simple and transparent: 'two' plus the suffix '-some,' the same '-some' found in 'threesome' or 'foursome,' which comes from an Old English ending meaning roughly 'a group characterized by this number.' No hidden plot twist here — it's been doing quiet, obvious work in English for centuries.
