BILLIE PIPER left a US chat show host blushing as she explained to him the meaning behind some British slang words.
The former pop star turned actress appeared on the Carson Daly Show to promote her TV series "Secret Diary of a Call Girl" and gave her host a guide to some of the lingo.
After telling the former MTV presenter she doesn't mind revealing a "little more arse than boob" in her role, she then explained what some of the terms used in the show meant.
Piper, 26, who said she hung out with call girls to research her role, told Daly: "Bonk is like shagging, like sex.
"Cheeky is kind of cute and seductive, but not trashy, not seedy. There is one called 'sploshing'. It's basically making love to food.
"It's not like dipping sauce and condiments. You pay your standard rate and you get that."
