In Catalan/Valencian we say “bona cara i bons fets” for people whose appearance matches their actions—but I suspect your wine-stained classmate would have her own proverb: “tall girl, quick hand.” The misdirection here is delicious. We’re set up for warmth and get a slap instead. That “soft, mushy ‘r’” is such a specific, almost tender detail for someone about to prove she’s anything but soft.
