Videos of teenagers dressing up as grandmas wearing medical masks to buy alcohol has gone viral.
This "prank" has taken online platform TikTok by storm, as teenagers share their experience dressing up and using a fake ID to buy alcohol.
"When you realise you can use anyone's ID to buy alcohol underage because they can't see your face," one user wrote.
"PSA: use your fakes as much as possible [right now because] if you wear a mask they can't see your whole face lol," another user posted.
The videos on TikTok, with around two thirds of users aged between 13 and 24, have gained millions of views.
It is not known where the videos come from but in the US and UK, many places have made wearing face masks in public mandatory.
One TikTok video with over 1.5 million views shows her walking to a car park with a bottle of pink liquid, wearing a baggy jumper, wire-rimmed glasses, a babushka headscarf, and wrinkles drawn on her face.
Another video with over two million views shows a brunette in a headscarf and glasses, and a floral skirt, later twerking on the side of the road holding a bottle of wine.
"Attention teenagers:" wrote a Twitter user, "now is the time to use your fake IDs wherever you can. Just throw on a mask and see if they can tell it's you or not on the ID! It's a fun game for you and your friends."
According to the TikTok community guidelines, TikTok will remove content that promotes criminal activities including 'content that offers the purchase, sale, or trade of unlawfully acquired goods.'
"TikTok is a platform for positive, creative self-expression, and keeping our community safe is a top priority," a TikTok spokesperson told Insider. "Our Community Guidelines make clear what is not acceptable on our platform, and we use a combination of technologies and moderation teams to identify, review and, where appropriate, remove content that violates these guidelines."
The videos have since been removed from TikTok.
