ACE - a word to describe/call a person who you like. They usually carry themselves with confidence and cockyness.
Just like in a card game you always want the ACE, in life you always want the ACE. They know you before you let them and you share the same values.
In an ideal world you would be perfect for eachother. however due to the nature of the game you only get the card your delt, which leaves you wondering how it would have played if you just got that ACE.
