1 definition by RobotLove

Zygote is a way to refer to very young people. Since the "real" definition of a zygote is sperm + egg; zygote is a slang version of referring to a very young person.

Often it is a more extreme version of the term "fetus," which is also used to describe young people.
Look at that little girl; she's not even yet become a fetus, she is a straight-up zygote.
