What does it mean?

It pretends to leave the choice to a coin toss, but heads means your place and tails means theirs, so either way you end up together.

How to use it

Cheeky, for someone you're already flirting with or a partner. Too forward for strangers.

How to reply

Coin landed on its edge. You're going home alone.
