Panini having the audacity to tell Chowder he's the clingy one is a form of gaslighting. She's the one who's clingy and obsessed with him and constantly stalks and harasses him. She doesn't get Chowder's "I'm not your boyfriend" message into her thick skull.

What's so fucked up is that Chowder and Panini are a married couple with many kids in the series finale.
