An Irish blogger has unleashed the latest online craze on the country with a tricky tongue twister that is taking over Instagram.
The challenge created by Instagram influencer Terrie McEvoy has taken over with thousands of people attempting the difficult phrase.
McEvoy has challenged people to say: "A box of biscuits, a box of mixed biscuits and a biscuit mixer."
Some of our colleagues tried the tricky phrase and you can see the results in our video above.
The challenge was set on Thursday after an Instagram filter used by McEvoy challenged her to say a tongue twister.
Since uploading her 'box of biscuits' challenge the influencer has been sent hundreds of videos of people attempting the challenge.
On one video she said: "OMG I'm laughing all day at everyone's tags!!! You're all so fun."
And last night McEvoy and her fans challenged Scottish heartthrob Lewis Capaldi to try the challenge.
The singer is known for his sense of humour and has viewed McEvoy's story but has yet to upload his own attempt.
Fans believe he's trying to perfect the tongue twister before uploading with one fan saying: "I wonder is he perfecting it before he uploads? Love him, gas man!"
If you have funny videos of your attempts at the challenge you can send them to us on Facebook.
