look up anything, like your first name:
1. superfecundation
(n) The term applied to the exceedingly (depending where one lives) rare situation where two (possibly more) seperate eggs from a woman are fertilized by sperm from two (or more) men.
Chan never did know why his fraternal twin brother was black until he heard of the term superfecundation. He never looked at his mother the same way again.
