Social media platform Snapchat may have crept up on you but with 100 million daily users and 8 billion video views per day, the pressure is now on grown-ups and companies to start using it.
It's the preferred social media platform for millennials -- those born in the 1980s and 1990s - and allows you to send a "snap" – a picture or video – to people. As soon as someone reads the snap, it disappears. But users can also post a "story" – a public collection of snaps that disappear after 24 hours.
Using Snapchat can be baffling to many, but never fear, CNBC has this handy guide.
Join with friends
If you've downloaded the app but haven't yet signed up, do it with a buddy.
There's nothing worse than joining a new social media platform and not having any friends.
"First talk about it in social circles and join it together," Dominic McGregor, co-founder of marketing agency Social Chain, told CNBC by phone.
Be a follower to start with
When you join Snapchat, don't feel pressures into snapping right away.
Follow some celebrities and brands who know what they are doing.
"If people are cautious, join brands and see how they are using it and that is a first step and a good one because now Snapchat has so much content on it, you can go on there and just be a consumer as opposed to a contributor," McGregor said.
Be silly, be yourself
On Instagram you're used to seeing a beautifully taken pictures of appetizing food with loads of edits. On Facebook, people's posts are well thought out. But on Snapchat, the key is not to take things so seriously.
Be raw, be spontaneous and most of all have fun.
"Allow yourself to be a bit silly and frivolous. A lot of fun has left Instagram. I know people who spend hours nursing over what to write on Instagram, and that's not the point of social media, it should be messy and silly," Ben Tyson, joint managing director at social media agency Born Social, told CNBC by phone.
Also, shaky videos, wonky pictures, drawing over your snaps and using emojis are encouraged.
Snapchat allows you to really present yourself in the moment with no pressure, a Snapchat spokesperson told CNBC.
Don’t follow your kids
"As an older person, a good tip is to not follow your kids. Snapchat is the most personal network. Everyone has everyone on Facebook. Twitter is for everyone. Snapchat is one you keep very private, you keep to your closest friends as it's such a way into your life," McGregor said.
The experts also advise thinking of Snapchat as one of the most private messaging apps. Instead of texting a message, you can instantly send videos and pictures of exactly what you are doing.
"Don't invite just anyone to follow you, keep it as your best friends," McGregor added.
"Only have friends or connections on Snapchat who you trust not to screenshot what you send them, not because you want to send them naked pictures, because those are the people you would show yourself doing stupid stuff," Tyson advised.
Vomiting rainbows is fun
Snapchat can recognize your face and overlay fun moving images. It could turn you into a dog or allow you to vomit rainbows. But that's a good thing.
"It's a very good way to keep fun communication up with your friends. It's new, it's exciting. Anything about Snapchat is a way to express personality," McGregor said.
