1.
Slang. An asexual person who experiences romantic attraction. The term 'Ace' (short for asexual) is used by asexuals to describe themselves, much like the modern day self-describing usage of 'gay' by homosexuals. Calling yourself an Ace of Hearts means that while you are asexual, you still feel romantic attraction. On the other hand an aromantic asexual, that is a person who does not experience romantic attraction, would describe themselves as an Ace of Spades.
"I thought that guy was an Ace of Spades because he never dated anyone, but last night he asked my sister to go on a date with him. I guess he's an Ace of Hearts after all."
