What Lazaro said depending on how you use the word can be a term of endearment, it also is used by people as a way to intimidate someone and rudely. The tone and inflection in the way he said "no problem Boo" was frankly meant to be flippant.
Myself people know not to call me Boo. I don't find it funny or endearing.lol calling me Boo is akin to waking a dragon,lol.
Lazaro's is a nice kid,but the excuses need to leave and so does he.
