look up any word, like bukkake:
 
1.
for when someone dumps/splits up with their partner giving little/laime or no reason at all, the other half not knowing that they have been 'dappered' in most cases

or when someone has made someone look stupid for being an idiot or being out of line

mainly for a group of friends to talk about IE group of males or females
i didnt want to see her any more so she got dappered
that guy just dappered himself for being an idiot
