When an actor/actress is cast for the same type of role over and over and is almost always the douchiest character.
I'm so tired of seeing Matthew McConaughey play the same character in every romantic comedy, that guy has been douchecast!

A portmanteau of "douche" and "broadcast" that describes the act of talking about things the douchecaster thinks makes them sound awesome, so loudly that they are overheard by everyone nearby.
"I wanted to get some reading done on the bus, but this guy in front of me was douchecasting his opinions about the local music scene so loudly that I couldn't concentrate".
