"Sell out" means when someone compromises their beliefs or values for money, fame or personal gain. It is used to describe someone who was once loyal to a cause, but has given up their principles to benefit themselves. For example, if a musician changes their style to become more popular and make more money, they could be accused of "selling out". Similarly, a writer who changes the plot of their book to make it more commercially successful may also be accused of "selling out".
