What is Massie's riddle thingy tat she asked Kuh-Lair at the first día of skl at OCD??

Massie : Kuh-laire, did i invite tu to my BBQ?
Kuh-laire (Claire): No.....
Massie : Then why are tu all up in my grill?!
*Exchange of high fives throughout the pretty commitee* <3

She says, "Claire, did I invite tu to my BBQ?" Claire says no. Then Massie says, "Then why are tu all up in my grill." Hope this helps I watch the movie like 24/7.
