Laying one's cards on the table
Laying one's cards on the table was a phrase proposed by Parth, as a replacement for the traditionally GLBT adage of "coming out of the closet". It was proposed in this post during a discussion about replacing said adage, and seemed to gain some support from other AVENites.
It is a reference to a game of cards, for the main purpose of referencing the term "Ace", a popular term used to describe an asexual. Beyond this, it represents showing your hand to the world; no longer hiding the proverbial cards. It is a phrase already used to describe a revealing, and as such it can be adopted fairly easily.
