A brother complex is basically the same as a sister complex but for one's brother.

Occurs when a girl of high school age, likes a member of the opposite sex at the same high school age, however when the said member of the opposite sex is also interested, and asks the girl to a dance or movie, the girl declines somewhat politely putting off that she is not interested even though she is interested. Further, she wants him to make a move, but does not want him to make a move, putting the boy in an impossible and lose-lose situation; forcing him to make a choice between rejection, or isolation. The reasoning behind this complex is not yet known.

To have a Achilles complex is to wish or bring about death to those who have seen you at your weakest or have humiliated you in anyway.

A mild complex would just have you hate these peoples very existence but not necessarily wish for their death.

Taken from the character Achilles de Flandres from the popular book " Ender's Shadow" by Orson Scott Card

The Urinal Complex presents itself in situations when subjects have to choose their spacial proximity to another subject. Subjects will choose to separate themselves from others in public areas. The condition usually manifests itself in parking lots, restaurants, and most importantly restrooms(usually male).

A Driver's Complex is contracted after one learns how to drive. It is the need never to sit in the back seat of a car ever again.

Symptoms include challenging legitimate shotgun calls and picking fights with the person in the front passenger seat.

a type of complex where a person makes everything more awkward than it is, calls everyone a "creeper", has shitty social competence, and snubs people that are different from them. It's not that other people are weird, they just freak out at everything and make situations more tense than they really are.

A complex where someone sees everyone and everything as "awkward" or "creepy"--words they use about 50 times a day. They construe ordinary, benign strangers as foreign, distant, and obtrusive, and regard unusual events outside the realm of their own standards & norms with an unreasonable amount of incredulity, disdain, or even alarm. Because of this, they often become avoidant, hesitant, and isolated in public situations, and so ironically, they become the most awkward and creepy people. Their construal of other people becomes a self-fulfilling prophecy when everyone meets their awkwardness with avoidance and mistrust--everything characterized by a creeper. Thus, they really do live in a world of creepers with everything becoming "awkward" and "creepy", hence, the "Creeper Complex".
