What does the sneezing emoji mean? If you're on TikTok, it apparently designates something as 'sick' – jargon for awesome or excellent. Yes, I'm confused too, and, like many people, I tread very carefully around these colourful icons.

Perhaps you are like me, a 40-something man befuddled by these arcane icons. But emojis are more than a youth fad. They play a growing role in online communication, especially during the hybrid work/collaboration era, and companies should take them seriously. Part of that is to establish what they mean within your organisation.
