fifaitus 

That time of the academic year when every male doesn't show up for school/college due to the latest release of FIFA Football/Soccer game. The name originates from a mixture of FIFA (International Federation of Association Football) & 'itus' (a common ending to an illness).

Teacher: Why didn't you turn up for class?

Pupil: Sorry Miss, I had a terrible case of fifaitus.

Fifaitis 

The seemingly real "switch" of winners in sports games back and forth in a grudge match, particularly in Fifa or Madden.

It's possible to win when you should lose, but it's harder.

Person 1 and Person 2 are playing Fifa on their home console.
Person 1 starts off with the "upper hand" and plays with ease. This would mean that Player 2 has fifaitis, and next match, Player 1 will have it.

"I would have made that shot if it wasn't for Fifaitis"

Also, see maddenitis
