Now Viewing: twincest


Tag type: General

incest that happens between twins.

Incest involving identical (monozygotic) twins necessarily involves same-sex relations; fraternal (dizygotic) twincest could result in either hetero- or homosexual pairings.

Applying this tag to triplets and other such siblings that came from the same multiple birth might get confusing; do so at your own peril.

The word itself is a portmanteau: twin+incest=twincest (which, you should note, cannot be spelled without win).
