The nigga did a Hit 'n' Run. Now he has a baby mama.
The act of farting, usually a SBD(Silent But Deadly) and rolling out(F.R.O.N.), and leaving before the stink gets to people noses so they won't suspect you as the farter.
Example
John was at dinner when feel overwhelmed him. He had to fart. John stupidly assumed his fart would go unnoticed. John released the SBD. After ten long seconds, John's mother smelt the fart. As a southern lady she sat in the fart not announcing it's presence. John's dad on the other hand, screamed at John the second the fart hit his nose. John was so embarassed he ran away and is now the hobo begging for money on your street.(THIS WOULD BE A PERFECT EXAMPLE OF WHEN TO USE A HIT 'N RUN.)
To romantically chat someone up, then bail before significant mutual feelings develop.
