The Next time someone calls you Mackeral (as in maquereau which is also french slang for pimp) thank them. It may mean you're doing something right. Turns out that mackerel and other oily fish contain long chain Omega-3 fatty acids that may short circuit cancer cells that refuse to die by other means.
My suggestion is to soak some mackeral in a reduced and cooled marinade of red wine, black peppercorns and shallots. Then lay on a bit of olive oil and salt. Slap those babies on the grill and don't worry about nothing. Know what I'm sayin? (Do I know what I'm saying?)
