Someone who has a very loud and outrageous voice and likes to think that they are the toughest customer around town. What he really doesn't know is that he is actually very insecure due to his passionate love he feels for his girlfriend (who is very hot). Sometimes they like to crawl on all fours and stick their rear ends into the air while howling like a hyena. The only way to stop them from doing this is to have them beaten into submission by their spouse. Begnidos also tend to have very quick tempers and are often referred to as mad bros.
