look up any word, like swag:
 
1.
Man oil is semen.
Johnny pulled his cock out of the whore's throat and sprayed his man oil all over her face.

2.
A man that knows what he wants and isn't afraid to chase after it. He is sexy, a bad boy, artistic, funny, and has a dirty mind. Women and men see past his strange name because he is so cool. He knows how to make someone laugh without even realizing it.
Why does Manoil always have girls all around him? Jealous.
