A small crush that you only have for one day. Most common place for this to occur is at a college visit, but may also occur at a concert, or while traveling, but usually only counts if you see the person on more than one occurrence that day.
While visiting Ithaca College, Greg had a huge daycrush on the girl in his tour group with the blue hoodie, as well as the girl who stayed at the same hotel as him, as well as the girl in the Matisyahu shirt.
