Teammates that go to hockey games together ... feed each other???
That's exactly what happened when Dak Prescott and Ezekiel Elliott hit up the Dallas Stars game Monday night ... 'cause the QB fed his running back a whole bucket of popcorn!!
It all went down in Dallas' playoff game against the Preds ... when cameras caught the two Cowboys stars taking in the action.
Zeke, of course, had to hit the jumbotron with his famous "Feed Me!" celebration ... so Dak obliged -- making an entire bucket of popcorn rain all over the RB's face!
