You know roller coasters are not your thing... when this happens

A man decided to take a rollercoaster ride at the Everland theme park in South Korea and his hilarious facial expressions were captured on video.

A clip uploaded on YouTube shows how the man starts to take deep breaths and close his eyes as the rollercoaster moves uphill.

When he reaches the drop and is unable to control himself any longer, he starts to shout. His mouth is also clenched together to bite back the fear.

Throughout the ride, he manages to keep his eyes wide open -- despite looking as if he is about to cry.

We can see the relief on his face once the ride comes to an end.

Watch the funny video below to see the look of terror in his eyes and funny facial expressions.
