US slang that references childhood:

Cooties are an imaginary affliction from childhood.

When children reach the age where they notice the sexes are different the children claim a member of the opposite opposite sex will give you "cooties" if they touch you.

Its a way of little girls telling other little girls not to play with boys and vice versa

Cooties are negatively charged particles. They are not the same as germs, or else they would not have different names. If you get too close to a cootie source you may be sucked into a cootie force field. Therefore stay away from all cootie sources i.e. boys.
I cannot come in contact with George because I do not want to be trapped in a forcefield of cooties.
