The marmion challenge is when students, particularly young men refrain from self-abuse, or "masterbation" for the 40 days of lent, and if they fail they simply say, "I'm out."
Guy 1:"Hahah, are you doin the marmion challenge?"
Guy 2:"yea, 3 days in and goin strong."
Guy 3:"I'm out..."
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?!
