What does the taco burrito nacho thing mean from the clique movie?

I'm going 2 break this into parts 4 easier understanding.

In the saying, each food represents a group of people or a person, so I'm going 2 use equations.

TACO AND BURRITO= Massie, Alicia, Dylan, and Kristen

NACHO= Claire

Massie says, "Conversation between taco and burrito, Nacho!"

"Nacho" sounds like "Not You."

Massie meant,"Conversation between me, Alicia, Kristen, and Dylan, Not You!"

nachos should leave tacos and burritos alone :)
