Braincest

In certain circumstances, two children will be born, sometimes even from different parents, and they will be siamese. However, not siamese physically, but mentally. If such children with siamese brains partake in any physical activities, it is called braincest.

Braincheck

When a girl is dying to give you some head but you just aren't in the mood for it -- you ask her for a braincheck.
