This gesture, typically seen in fiction such as anime, manga, rather old films or dramas, and typically done by young boys, indicates one's pride, confidence, and/or [[shy]]ness.

Sometimes a similar concept is achieved with older characters, the difference being is that they usually rub their [[facial hair]] or other part of their face instead, probably because nose rubbing is considered more childish. 

Use [[wiping nose]] for wiping blood or a [[runny nose]]
