A teenager pretending to be 'bad' learned a lesson. 

A post on a Korean online community board titled, "Teen's showing off drugs," tells a recent story of a teenager who uploaded a photo of syringes on his Kakaostory with the caption, "We're doing drugs at karaoke." A friend of the teen student saw the post and called the cops, thinking that the teen was in danger.

Police officers rushed to the karaoke, but it turned out the "drugs" in the photo were just empty lab syringes without needles. The teenager wanted to seem rebellious to his friends and decided to fake his 'badness.'

The incident ended with no one getting arrested, but the teen had to wait for his parents to come to pick him up in order to go home.
