the.com/coin toss

The universe's way of deciding things while letting everyone pretend it's fair.

means A decision made by flipping a coin and letting whichever face lands up settle the matter, usually when the choice feels like a fifty-fifty gamble anyway.

from Straightforward compound: 'coin' plus 'toss,' describing the literal act of flicking a coin into the air to let heads or tails pick a winner. Coins have been used for random choice for a very long time — the Romans reportedly played 'navia aut caput' ('ship or head'), betting on which face of a coin showed. The specific phrase 'coin toss' as an everyday English term for an arbitrary decision — official or casual — is a more modern usage, now as likely to describe a sports game's opening ritual as a metaphor for any toss-up situation.
