Well, in organic chemistry, the definition is a bit more simple than it is when you're referring to redox reactions. Since you're dealing now with only organic compounds and not inorganic species, you can say, with respect to $oxygen$, that:
 $\sf \color{blue}{Oxidation}$ is the gain of oxygen, while $\sf \color{red}{Reduction}$ is the loss of oxygen.
