Cussing in Spanish

I've lived in South America for 3 years now and I've learned to insult someone in more ways than I ever thought possible.  Naturally, I blame my husband (a native Spanish speaker with an artistic flair for insulting unwitting strangers doing stupid stuff), however, some of our friends, after witnessing mini-displays of these flare-ups, have laughingly told me that I've channeled my inner Latina.  My Angry Spanish was the first Spanish that was really fluent for me.  I couldn't partake in a general conversation to save my life but try to screw me over because I'm a Gringa (white and female...both can have their barriers) and I could tell you what the problem is, why it's a problem, what you are going to do to fix and show you why what you are telling me is the stupidest thing I've ever heard and why you are an idiot for buying into it. In the beginning, the Angry Spanish was activated in 2 situations:  (1) Someone trying to screw me over and (2) getting screwed over by a nonsensical rule that someone put in place without taking the millisecond required to think through the consequences (South American bureaucracy).  Unlike in the US, I have found that activating the Angry Spanish is a very effective way of getting things done...something those who have born here have known since birth.  After 3 years in South American, my Angry Spanish has become more multi-purpose.  Interestingly, my temper is shorter and flares up as quickly as it cools down and just driving usually entails a artful display of vernacular aimed at people blocking traffic, parking in the middle of the street, cutting me off, not using turn signals, blind traffic cops, and people in fancy cars with their kids flopping around the front and/or back seats. (I still don't understand why it is so hard to put a kid in a carseat or make them buckle-up).  Is Spanish such a much more romantic, eloquent sounding language than English, making muttering (or yelling) insults about someone not seem quite so harsh or do people just take stupid stuff to the level where such outbursts are necessary to bring "reason" back to the table?   (Or has my husband just rubbed off on me?)  I'm personally torn on the issue.  All I know is that Angry Spanish works....and I sometimes wonder if part of its power is that it is coming from a Gringuita who 5 seconds earlier was all sweet, calm and polite....until you did something stupid and ticked her off.

Any ideas?
