The first boss of the game lets you do this easily.
Trek your way through the level and make it to the boss.
Then, wait till he is low enough on the ground for you to be able to land a jump kick on his back (Jump kick is double jump then down+a), make sure you stay towards the middle of his back so that way when he lifts up, he doesn't knock you off. He does tend to jump a lot when he has a lot of health, so wait til you wear him down a bit to be able to successfully do this achievement.
I hope this helps.
Update:
It has been confirmed that you can, indeed, jump kick your teammates for the achievement.
So you can use either method.
