What does 'de nada chico' mean in English?

The meaning in English of the Spanish phrase 'de nada chico' is the following: '[It's] nothing, man'; 'No problem, man'; or '[You're] welcome, man'. The Word-by-Word translation is the following: 'de' means 'from' or 'of'; 'nada' 'nothing'; 'chico' 'boy' or 'very young man'. Unlike the equivalent in Spanish, use of the Word 'boy' may be seen as condescending and somewhat insulting in English. So it probably works best not to go for a literal translation in this case.
