The process of wasting time with another one is infatuated or sexually attracted to, usually of the opposite sex. Most of the time, this takes the form of typical 'small talk', boring activities such as going out to dinner or to the movies, et cetera. This is usually to distract each other from the reality that they have nothing on their own, though usually women are more oblivious to this due to cultural norms. In real relationships, this can just be a form of killing time, because it's not really needed for any meaningful interaction. Typically, this lack of deeper bond is the reason why relationships split up, but the distractions keep it going for awhile so it's a big painful shitstorm when one or both parties realizes that fairyland is a fake place and that you have to WORK for a REAL relationship.
