This seems to cross all regions and groups throughout the US. People just stick an extra "s" at the end of a word when it is simply not needed, at best--tellingly ignorant at worst. Even well-educated people (though obviously not in language) carry with them a bag filled with extra letters "s" should some poor unsuspecting word seem to require one.
A common one around this time:
"Happy New Years!"
No, just one. Happy New Year.
Many people will be watching the World Cup this summer:
"Hey referee! He's offsides!"
No, he's offside. There's only one side to be off. If he were on the other side, he wouldn't be offside! (Not to mention the uber-trained, beyond elite FIFA Assistant Referee is far more likely to be right than you).
There are worse examples, such as "...going to Wal-Marts."
A million more examples. So why the extra "s"? Any exampleses that are commons in yours necks of the woods?
