Question

Answer

The only time I've heard this word used in my entire life is during rugby matches.

Answer

I hope I understand your question correctly (my Spanish isn't too good), but I think you want to know what the word scrum means?

The word scrum, as far as i know, can either refer to:
1) A manner of restarting play in a rugby game
2)A method of software development

So it depends on the context I guess.
