If you've searched the dictionary for the words on the left, you're not alone - they're Merriam-Webster Online's "Most Looked-Up Words Not in the Dictionary."

Without a dictionary handy, a Daily reporter asked students what they thought of these words. Some were certain that none of them were in the dictionary. Others weren't so sure.

"Well, I say 'ginormous,' " biochemistry sophomore Jenny Buehler said. Buehler and three friends, who were sitting in the Michigan Union's basement, agreed that ginormous is a commonly used word. Chemistry sophomore Alison Ryan said if ginormous isn't in the dictionary now, it should be.

They were confident that "confuzzled" and "chillax" were not in the dictionary, but "cognitive displaysia" sparked debate.

"I think I've heard it in psych," LSA sophomore Noel Bezaire said. Bezaire's friend, LSA sophomore Kausar Hafeez, pointed to the definition of the word on a list that a reporter provided them (n. the feeling you have before you even leave the house that you are going to forget something and not remember it until you're on the highway) and encouraged her to think again.

Bezaire insisted that she had heard of the concept in class.

Although "cognitive displaysia" is a made-up word, it has caught on in the blogosphere. Googling it reveals that it is the title of several blogs. In their entries, the bloggers confess that they are habitually forgetful and paranoid about it.

Hafeez said online communication might be to blame for the creation of new words.

Hafeez said that when having online conversations, her friends often use words she hasn't heard before. She said that when she is in this situation, she usually refers to an online dictionary, which may be the reason others look up words like "phonecrastinate" or "woot".

Another group of students had similar problems identifying the real words when presented with the 10 words and their ostensible definitions.

"I don't think any of these are actual words," LSA junior Esther Park said. But Park said she couldn't be sure about "cognitive displaysia" and "confuzzled" (adj. confused and puzzled at the same time).

Park and her friends suggested that some of these words might be included in urbandictionary.com.

They were right. Of the 10 words, all except "cognitive displaysia" were included on the website.

In comparison to urbandictionary.com, Merriam-Webster proved to be scant in its explanation of some words. Merriam-Webster's definition for "slickery" (adj. having a surface that is wet and icy) wasn't nearly as sexually explicit as the definition provided by urbandictionary.com (adj. when a woman's vaginal area becomes wet due to sexual arousal).

The use of slang has a colorful history. For example, urbandictionary.com describes the etymology of "woot" as a truncated expression coined by players of Dungeons and Dragons who exclaimed "Wow, loot!"

Dictionaries generally add new words when they enter common usage.

LSA freshman Angela Lin said dictionaries shouldn't adapt to the popular use of certain words.

"I think the dictionary would get really thick after a while," Lin said.
