I wouldn't start to worry too much about his hunger strike just yet. Weigh him regularly and make sure he's not dropping too much weight.
However...
This is not a good idea. You aren't going to piss him off enough to get him to strike a mouse. As a widely general rule, ball pythons don't roll like that. Even if you were to get a defensive strike, he probably wouldn't eat it afterward. What you may end up doing is causing him more stress, which leads to BPs that don't eat. Offer up the mouse, but don't try and tick him off with it.
