"I can't believe you!" Ron hissed angrily at him.
"Who's the jealous little shit?" Xander asked clearly unimpressed with Ron's attitude.
"Language!" Hermione blurted out reflexively.
"Keep your racism to yourself," Xander said firmly.
"What?" came the confused response from half a dozen people.
Dawn sighed. "There is no such thing as a dirty word, the words that are considered such are just holdovers from medieval cultural imperialism where the nobles were trying to stamp out a culture and their language to force the locals to conform to their ways."
"Yes, however the majority of the people we interact with won't know this and simply assume we are ill mannered ruffians with low IQ's if we talk that way," Hermione explained.
"Huh?" Ron asked dumbly.
"That shite won't fly," Fred translated.
"So talk decently or expect to get smacked," George finished.
"Bitch!" Xander added cheerfully.
"Dad!"
"End strong honey," Xander said. "Plus the irony is hilarious."
"He's good," Fred and George chorused.
