heartcake

The term "heartcake" is most commonly used in English as a verb or adjective expressing something akin to "I feel awesomeness in regards to such-and-such" or "that idea is the awesomeness," and this word is also often alternately expressed in shorthand by the use of two emoji "💜🎂" or "💜🍰."

This term came into use in early 2016 to replace the use of simply "heart" "💜" in many circles online and irl. ;-)
