Pour one out for Keith Smith's poor toilet ...
The Atlanta Falcons fullback admitted this week he has a SERIOUS affinity for Chipotle ... explaining he gets bowls from the Mexican food joint 4 or 5 times a day!!
"You probably won't believe it," Smith said on the "Endless Hustle" podcast this week. "But most people who know me know that it's legit."
The 6-foot, 240-pound NFLer explained he uses the restaurant as a way to sort of meal prep.
Smith -- who turned 28 back in April -- says he gets his bowls compartmentalized .
