Me cago en... Common expressions in Spain and Cuba
 

I rented a movie in Spanish from Spain today. It's called Guerreros. It's the true story of a platoon of Spanish soldiers sent to Kosovo in 2000.
It's very good. Anyway they were saying these expressions that my Cuban wife uses.

Me cago en tu madre!:eek: I sh*t on your mother.
Me cago en tu padre! I sh*t on your father.
Me cago en la mi*rda! I sh*t on (the) sh*t.
Me cago en Dios!:eek: I sh*t on God.

They are said when somebody is very upset naturalmente and are not to be taken so literally.

These expressions probably have very little meaning for limited Spanish speakers but they are very typical of Spain and Cuba. Very colorful to say the least. LOLROTF!:D

Don't use them with people you don't know. Actually my advice would be to not use them at all but just so
you know what they mean.

Well in South America are common too, here the most common of that kind would be:
"me cago en vos", then it would come "me cago en Dios"; the rest aren't too common, we use another expressions a little more stronger.

They sound so rude and ugly.

And what would those other stronger expressions be?
