"Hey, Sweetie Belle? What's fillyfooling?"
Sweetie jumped and turned to stare hard at her innocent-faced pegasus friend. "Where did you hear that word?"
Scootaloo shrugged innocently. "Apple Bloom mentioned it when she was talking about Applejack the other day."
Sweetie Belle's eyes widened. "Whoa. Applejack's a fillyfooler?"
"I guess. But what is it?"
"Well," the unicorn filly hedged, flushing, "it's, um... well, Rarity says it's a 'derogatory term', whatever that means..."
"That's not helpful," Scootaloo complained. "I mean, what is it?"
"It's, um - oh, look, why don't I just show you..." Without warning, Sweetie Belle leaned forwards and gave Scoots a quick peck on the lips.
She'd intended it to be a mere demonstration, but on second thought, it felt kinda good... Her heart thumping out of her chest, the unicorn wrapped her hooves around her friend and pressed their lips deeper, only bothering to come up for air several seconds later. "T-there," she stammered, still in shock at her own audacity. "D-does that answer your question?"
Scootaloo stared at her in open-mouthed awe and then broke into a grin, her wings flaring open slightly. "Can we try that again?"
