Spellexia 

A virus that causes one to struggle to spell words correctly. In extreme cases, those infected with this virus can turn disturbingly violent! Some have been recorded to have stolen bodies from funerals, torn of their limbs, and used them to repeatedly slap people in the face (hard enough that the arm bends the wrong way) while they repeat a "spellexic" mantra "there! they're! their!"

There are currently no known cures...

EXAMPLE 1
Person 1: IT WORKS! YOU SAW HOW AWESOME THE STRIPES LOOKED. YOU ARE IN DENIALLLLLL!!!!!!!!

Person 2: Denial? I think ur spellexia is acting up again because that most definately looked stupid

Person 1: denial is spelt denial. you are on drugs...

EXAMPLE 2
Person 1: Marc's attitude is so obese.
Person 2: Do you mean OBSCENE?
Person 1: Oh yes, that is what i mean, darn my spellexia for acting up again
