A person that is both your best friend and partner. When you have graduated to this level in a relationship calling each other, dude, bro, bud, man is totally acceptable because neither of you are insecure about your love. It’s totally cool.
1. A dumb person or an idiot; 2. A person who stares too much.
Root of the word: The word "baboso" is a Spanish word that when literallytranslated is used to identify a person that slobbers too much. Because slobbering is usually the result of ones mouth hanging open for a prolonged period of time, the person is identified as an idiot, or someone who stares too much.
