Verb. More than "to like" but not necessarily "to love." It could potentially be love, but it does not have to be. This word comes from when people write I (then the shape of a heart) Shannon, or some other name. People would always pronounce the "heart" when it was supposed to mean "love." This would always get annoying, so instead of blocking it out and telling people they are retarded and need to be shanked
, it became embraced as its own definition.
I heart Shannon Marie.
