Rams running back Kyren Williams came to his teammate's defense during "Monday Night Football" ... but he had a pretty unique way of doing it -- poking his Dolphins opponent's ear in a bizarre in-game moment!!
It went down during the second quarter of the primetime matchup ... after Miami defensive back Kader Kohou gave L.A. wide receiver Demarcus Robinson a shove -- which Williams didn't take lightly.
Instead of escalating the situation further with a shove of his own, Williams responded with a wet willy-esque tactic.
