The official term for the Jak and Princess Zelda pairing.
In particular, Jak is defined as the protagonist (who is not furry) of the Jak and Daxter series, and Princess Zelda is the not damsel in distress from the Legend of Zelda: Ocarina of Time.
It could also be called 'Zak,' but for some reason it made people think of Zack Fair, who is certainly not Jak and certainly not Zelda and certainly not Jakelda.
"Jakelda is so cute!"
"I sometimes imagine Jakelda is what would happen if Jak and Zelda had babies."
"What? You made a Jakelda tag? Are you serious?"
