When someone believes something to be the exact opposite of what it actually is. Such as when someone believes that someone whom they stalk and harass both in person and in cyberspace, thinks only about him/her and misses him/her and loves and longs to be with him/her when in actuality they don't think anything other than you are a pathetic creep/jerk with no life who obviously has a lot to learn in the way of making and maintaining healthy relationships. These are often the same conceited creeps who make futile attempts to make the object of their obsession jealous because they are too ignorant to realize that people are not all like them and that people who are secure with themselves do not get jealous and see their actions as really really lame and pathetic.
ALL those men from El Minya are DELUSIONAL especially HeisamledbA, KalaM, RemA and the list goes on.
