“I love you” arms race 

When two (or more) people get caught in a loop of saying “I love you” with increasing intensity or grandeur.
Ex-
Person 1: “I love you”
Person 2: “I love you more!”
Person 1: “I love you most!”
Person 2: “I love you mostest!”
Ad infinitum

“Those two are disgusting together, they constantly get stuck in an “I love you” arms race.”
