A gamer
Gamering is like gaming but way more intense. It’s like if gaming was a sport and you trained for it like a pro.
My friend’s a gamering. He plays 10 hours a day and still hasn’t finished his homework.
My cousin says she’s a gamering. She plays Call of Duty and complains about the game more than the people in it.
My dad’s a gamering. He plays games and then yells at me for not playing them.
