Used to describe being targeted by a particularly clever insult or witticism that uses a portmanteau, or combination of two or more words, as a punchline. It can also be used sarcastically, for example after an especially weak pun.
The word is a portmanteau itself, of "portmanteau" and "owned." As a result, timely usage of the word can count as an example of itself.
"Dude, there's a poltergeist in my chicken coop!"
"Don't you mean a...poultrygiest?"
"Oh, shit, I've been portmanteauwned!"
when the government makes you think through esp that someone knows your whereabouts and is talking about you which distracts you from your daily tasks.
The portmanteau purloin put the majority of Americansliving paycheck to paycheck because they couldn't pay attention.
