Get the Heart-Onmug. The action of being in like, lust, or love with someone. Related to the act or statement to heart him/her. Generally accompanied by fascination/obsession with the individual in question. Typically used when the situation is too ambiguous to establish a true definition of what the relationship is....the fact that hearting is someone also sounds like the word "hurting" is an interesting coincidence, because sometimes hearting someone can be quite painful...
Girl: "I'm not sure he likes me"
Friend: "Well, based on his actions, I would say a good bit of hearting is going on. I think he'll ask you out soon..."
