Rapper The Game finds it difficult to contain his anger when on tour, because being on the road is too "claustrophobic" for him.
The Game - real name Jayceon Taylor - admits he sometimes physically assaults member of his entourage as a result.
He tells MTV.com, "Being on the bus is like being in a prison on wheels, man.
"It's nothing like being at home. You could be on here for 24 hours, confined in this little space and you start getting claustrophobic and when I start getting mad I just start pulling people out of their bunk and kicking them in the face and s**t.
"Life on the road, you got to be ready for it, and a lot of people don't know that. They think that being a rapper all you got to do is write a 16 (bar sequence), write a hook and then you in the video - you get the chains, you get the girls.
"But it ain't like that, it's a lot of hard work."
