If anyone in Milton Keynes still uses these 10 emojis, then they're officially old!

The worst offender is the 'thumbs up' symbol, which was as it was voted the single uncoolest emoji by 24 per cent of 16 to 29-year-olds.

Sending a red heart, an 'OK hand' or a crying face is also deemed to be deeply old-fashioned and something a young person would never do, according to the poll.

The survey was carried out by research and insight agency Perspectus Globaland it found the average Brit sends a staggering 76 emojis every week on their texts and social media.

But some are now seen as seriously outdated. In fact, 24 per cent of the young people surveyed consider the thumbs up emoji to be "cringeworthy", while 17 per cent said that the check mark signifying ‘done’ is seriously uncool.

Other uncool symbols the poo emoji, the 'monkey with hands over face' emoji and the 'clapping hands'.

Overall, the poll of 2,000 Brits found that the most popular emoji, across all ages, was the laughing face crying tears of joy, with 45 per cent voting in its favour.

The least popular symbol, again across all demographics, was the sinister skull and crossbones emoji - 28 per cent of people said it was their least favourite emoji).

It seems that emoji-mishaps are rife, as 78 percent of Brits admit they have innocently used a symbol, often repeatedly, before finding out it had a different, ruder meaning.

And using multiple emojis to make a text even clearer is commonplace, with 22 percent of people doing so in every message they send.

Evie Porter from Perspectus Global said: “With the average Briton sending 76 emojis a week, across multiple platforms, it’s clear that these symbols are now a vital part of our daily communication - on both a personal and professional level.

“Yet this research indicates the importance of assessing which ones you use. Unless you want to be seen as old fashioned, it seems wise to avoid the thumbs up symbol.”

The study also found that gender differences exist when it comes to emoji use.

While 26 per cent of British females said their favourite emoji was a smiley face with hearts round it, only 7 percent of males said the same.

And 28 percent of women said the emoji they liked using the best was the smiling face with hearts for eyes, compared to just 17 percent of men.

However, the research indicates that emoji use is now a very important tool for communication, with the majority of Brits claiming that an emoji (or string of emojis) can say a thousand words.
