Nathan, from London, filmed his five-year-old cousin's hilarious reactions whilst playing the video game "Rocket League," a vehicular soccer game.

The 5-year-old boy's mood switches several times from laughing and excitement to being miserable and crying.

As Nathan scores a goal on the video game, his distraught cousin drops his controller and starts sobbing.

Nathan, who filmed the video, told Newsflare: "My cousin from Ghana came over and was begging me to play games after I helped him finish his homework. As we were playing, I realised how funny his mood changes were and decided to film it."

This funny scene was filmed at their home in London on Sunday April 14. The 5-year-old's parents have granted permission for him to be in the video.

My cousin from Ghana came over and was begging me to play games after I helped him finish his homework. As we were playing, I realised how funny his mood changes were and decided to film it, my intention was just to show my family but I ended up putting it online, and it blew up.

He’s 5 years old, yeah he always reacts like this but this was the first time I caught it on video. We were playing Rocket League and it was filmed in London
