1. 本人 means "this person".  Chinese likes to use third person form to refer to oneself.  This is considered to be polite.  Of course it depends on the tone or the way it was spoken.  See #3.

2. 本 is also an honorific term for "I" depending on your social status. For example, 本宮 = This palace, is the royal "we" used by empresses and imperial concubines.

3.  It can also mean sarcasm to elevate their status.  

本姑娘不須要你的吻吻 = This girl (I) does not need your kisses.

本少爺不要你的錢 = This master (I) don't want your money.
