The combination of "legacy" and "seed". A legaceed is someone you have given birth to. They are both your seed (literally), and legacy (literally and figuratively). Additionally, a legaceed can be someone who is entirely unrelated, that you have "son-ed", such as a good friend.
Kim and Kanye's legaceed will probably be the Antichrist.
