someone who is married to two or more people at the same time
"The polygamist has problems in his marriage."
Individual who conducts a practice revolving around the matrimony to several other people at the same time like there is nothing remotely creepy about it at all.
Not only do polygamists get to switch out fuck buddies throughout the week with no penalties but they also are able to get a tax break for every wife/husband they obtain because marriages in most states are recognized as civil unions.
Is it creepy? Yes. But is it smart?. . . . . . . . :)
Probable polygamist conversations:
"Hey sorry wifey number 2! This is wifey numbers three's night to have passionate, bouncy love making with me, but we'll schedule a Wednesday canoodling!"
"Go fetch me a drink."
"Which one of us are you talking to?"
"All ya'll bitches! Now go get me a drink dammit!. . . . . . Ain't nobody got time for this -_-."
Usually a man (though sometimes a woman) who is married to both his wife and his video games. Any non-work (if he works, that is) or non-sleep (if he sleeps, that is) time is probably reserved for World of Warcrack, Evercrack, or some other mmorpg, resulting in the human wife either signing divorce papers or going to see Dr. Phil.
Wife: "Wow, honey, did you see that obsessed polygamist on the Tyra Banks Show? The guy even left his wife in labor at the hospital to play his game!"
Husband: "What? Listen, shut up for a minute, I'm doing a raid."
