marmite addict

a marmite addict is often very territorial over THEIR jar of marmite. Often results in fists being beaten against walls.
Signs of an addict...
1. expresses extreme concern over a missing jar of marmite
2. attacking relatives and housemates over the potential steal of marmite
3. irrational behaviour towards neighbouring objects when marmite fails to appear for a daily fix

I am not suggesting you stole my marmite just that you confused it with yours?!
