Rude words, they're pretty brilliant, no matter how old you get or how often you use them, they never get boring, and when you combine them with a swear it's just perfect.
But what's even better is when a rude word takes you by surprise, and no one on television knows more about that than Countdown's resident maths whizz, Rachel Riley.
Celebrating 10 years on the hit show, Rachel took to Twitter to share some of the rudest words she's ever had to spell since she took over the reins from Carol Vorderman, in 2008, right after graduating from the University of Oxford.
The 33-year-old posted a few pictures, with the caption: "Celebratory 10 years of rude @C4Countdown words as promised! Do with them, what you will."
And she did not disappoint.

From the 'C' word to 'twat' and from 'squirt' to 'noshed', the TV personality's post included all manner of swears and smut.
The flashbacks also looked back at the time 'perverts', cottagers' , 'vaginas', and 'todgers' all graced the famous blue board.
Her followers couldn't believe their luck, with hundreds commenting on the post.

One fan wrote: "Undoubtedly the best post ever!!"
Another said: "The best parts of all of these are @RachelRileyRR expressions."
A third follower added: "Completely juvenile and I giggled at each and every one!"
"This will never not be funny", wrote another.

Not everyone took the opportunity to snigger at the childish post, some actually congratulated the host for her special milestone.
One of her adoring fans said: "Well done Rachel reaching 10 years on Countdown."
Another added: "Congrats on making the last 10 years of #Countdown AMAZING Rachel, here's to the next 10 YEARS! Long may you reign my Queen."
This isn't the first time that Riley has spoken about some of the naughtiest words she's had to read out on the daytime show.

Speaking to the Express in 2017, she said: "Most of them are well-documented online but some one of the funny ones for me are growlers because it's perfectly innocent and you can get a definition of a bear.
"But then when Nick repeats it over and over and over, I'm sure the younger viewers - teenagers - might know something else quite funny. They're the ones that get me."
Congrats, Rachel, you wonderful woman.
