Definition
I've been trying to find a good definition for this, best yet is from Century Dictionary
 * A geometrical singularity, the reciprocal of a node. In the case of a plane curve, it is a multiple tangent; in the case of a torse, a multiple plane; in the case of a surface, either a plane having a conic of contact or a torse bearing two or more lines of contact.
