Translation of shithead in Spanish

I thought it was great to hear from you. I would love to help you to learn Spanish. I'll write in English and you tell me the Spanish translation. I think that you're good enough for that exercise.
The words will mostly be easy. I would prefer full sentences and not just short clauses with the article, the noun and an adverb/adjective. Do you think you could do 1000 sentences per working day? This way we could finish quickly.
Thanks for the corrections and for accepting my friends request. You are completely right: Spanish grammar is simpler than German grammar. I was just looking for a job where both languages are required.
