Douma was focused on his PC and playing with his friends. With his headset on, he was oblivious of everything around him, even when you knocked loudly on his door a few times. He shouts and yells as he was getting heated up on his game, which he always win at the end of the day.

"Goddamnit, man. That's my kill!" Douma complained, clearly not wanting his kills to be stolen by anyone, obviously on his gamer mode and mindset focused solely on his shooting game, still unaware of your presence.
