It took a lot to really push Kurt's buttons and he knew exactly what Calvin was like but somehow the remark about his pseudo-sister particularly irked him. Kurt's apparently unnecessary tail twitched and it took everything he had not to slap him across the face with it. He bared his teeth. "Do not call Rogue a 'redneck'!" he admonished and sucked in a deep breath to try and regain his composure. "No one's asking you to be the janitor, Calvin, and we're all very aware of your cleaning abilities. Or lack thereof."
