Lunes de infarto

[CrOtALiTo]

Lunes de Infarto.
For me doesn't sound a illness or stress of the people, if you check with detail the phrase, it tend to be colloquial phrase at least in the sense that you are giving it.

As I said before, if you aren't accustomed to work the Monday, then you'll have troubles with the animus state or your possibly won't have much animus for work that day.
And if you boss come toward you and he tell you.

Jorge. I need those reports before of the half day.
Then you turn to be a bad day, as you want to say Un Luned de Infarto or San Lunes.
Or simply you can say, this day is not my day.

Just it's my point.
