A U.S. university has issued its annual list of annoying words, and those flexible enough to take selfies of themselves twerking should take note.

In addition to selfie and twerking, there was a strong sense among those who nominated words to this year's list that the word hashtag and term Mr. Mom had both run their course.

Selfie, a term that describes a self-taken photo, often from a smartphone, led the way among the more than 2,000 nominations submitted to Lake Superior State University's 39th annual list of words. 

Even President Barack Obama took a well-publicized selfie with other world leaders in South Africa for Nelson Mandela's memorial service, and Pope Francis posed with young visitors at the Vatican.

Since 1975, the list has grown to more than 800 words, many from the worlds of politics, sports and popular – maybe too popular – culture.

"The list is made up completely from nominations. We don't just sit around and think of words that bug us," said Tom Pink, a spokesman for the school.

List published annually

Twerk or twerking, a sexually provocative way of dancing, found a dominant place in parlance due to Miley Cyrus' performance at the MTV Video Music Awards.

Hashtag refers to a word or phrase with no spaces preceded by the pound sign on the microblogging website Twitter.

Others on the list include Twittersphere, t-bone, Obamacare, intellectually/morally bankrupt and anything "on steroids." People also tired of the suffixes -pocalypse and -ageddon used to make words such as snow-pocalypse or ice-ageddon.

And enough already with Mr. Mom, a reference to fathers who take care of kids. It's also the name of a 1983 movie starring Michael Keaton, although many stay-at-home dads these days don't like the movie stereotype of a clueless male.

"There were almost as many nominations for Mr. Mom as selfie and twerk,' Pink said.

He believes the title got traction again in 2013 due to news stories about the 30th anniversary of the movie.

Adversity and fan base – terms often used when discussing sports – got booed.
