Blake Harrison tried to impress on the set of The Inbetweeners film by speaking Spanish - but ended up accidentally using bad language.
Blake, 25, Simon Bird, 26, Joe Thomas, 27, and James Buckley, 23, who play schoolfriends Neil, Will, Simon and Jay in the hit TV show, filmed the spin-off movie about a lads holiday on location in Magaluf in Majorca and Blake tried to speak the local lingo.
Simon revealed to The Sun: "Blake has been all pretentious and tried to learn Spanish, which we were morally against.
"He was doing quite well so someone told him that the Spanish word for 'OK' and 'cool' was 'culo', when actually it's used for 'a***hole'.
"So there was about a week where he was going around saying, 'Ah Culo, thank you, Culo'. That's been my highlight, watching him going around telling everyone they're a***holes."
The actors all enjoyed filming the movie, which is released on August 19, and for some of them it was their first experience of a lads' holiday.
James, who is expecting a baby next year with Scottish model girlfriend Clair Meek, revealed: "I completely avoided it. Every single one of my mates went on about two or three. It just sounded like work.
"You had to be like, 'right, we've got to get up because we're going to go out tonight and we need to get this over and done with and then we could go back to bed'. It just felt like you had to go out for going out's sake. I like to sit down and relax."
