You need to do this on the level "Afterlife"
It's best to do this with a second controller and pick Father and Father
Set up the beginning of the phrase and try to continue it with (...) until you get the other part/s
"You unlock afterlife by completing the tournament with father"
Thanks to Skate 323 for pointing that out
You unlock father by completing the tournament with 5 different characters
Also the achievement will pop if you do it with your second player/controller as well
