From a crotch on fire to panties that refused to be worn, pop-culture catch phrases and buzzwords were particularly raunchy this year.

Here's a list of our top 10 favorites, plus a few more:

10. Firecrotch

Famous-for-being-famous rich kid Brandon Davis insulted celebrity redhead Lindsay Lohan by referring to her as “firecrotch” — and La Lohan was not amused. Davis issued a written apology a week later, but the expression — and the eponymous T-shirt — took off nonetheless.

9. Bimbo Summit

When Lohan and fellow underwear-shunning starlets Britney Spears and Paris Hilton decided to make the paparazzi’s dream come true by forming a brief, panty-free, photographer-friendly friendship, the New York Post headline "Bimbo Summit" circulated as one not-so-nice way to describe the threesome.

8. Manny

Britney kicked off another pop culture buzzword when she hired a male nanny ... aka manny ... to help her look after little Sean Preston. The studly Naval Academy graduate was no Mary Poppins — and seemed to foreshadow the demise of her marriage to Kevin Federline.

7. K-Fed/FedEx

Which brings us to K-Fed. Spears apparently became “fed up” with the sullying effect her aspiring rapper-husband was having on her image, and, according to legend, transformed him into her "FedEx" via text message.

6. 'SexyBack'/McPheever/Soul Patrol

Other stars had a better year than Britney and K-Fed. Britney's ex Justin Timberlake claimed to bring “sexy back” with his hit song "SexyBack"; thousands of Americans got the “McPheever” for sultry “American Idol” runner-up Katharine McPhee and whoever didn’t have the McPheever was on "Soul Patrol" for “Idol” winner Taylor Hicks.

5. Suri and Shiloh and Kingston, Oh My!

Tom Cruise and Katie Holmes also had a joyous year, as Holmes gave birth to their little "TomKitten," aka Suri Cruise.

But Suri wasn’t the only celebrity baby given an unusual name in 2006. Celebrity do-gooders Brad Pitt and Angelina Jolie produced Shiloh Nouvel Jolie-Pitt (also called "the most beautiful baby ever born"); Gwen Stefani and Gavin Rossdale welcomed Kingston Rossdale and Donald and Melania Trump greeted Barron William Trump.

4. McDreamy/McSteamy/McScuffle

It was also an eventful year for the cast members of newly minted hit show “Grey’s Anatomy.” Men enjoyed the famous three-way shower scene episode after the Super Bowl, and women across the nation went wild for doctors McDreamy (Patrick Dempsey) and McSteamy (Eric Dane). But tensions flared as McDreamy and Burke (Isaiah Washington) got into a real-life on-set McScuffle.

3. 'Don't Hassle the Hoff'

“America’s Got Talent” was a surprise summer smash, and also provided a comeback of sorts for David Hasselhoff. But that didn't make the European singing sensation all warm and fuzzy — the former "Baywatch" star issued the warning “Don’t hassle the Hoff” — and another T-shirt was born.

2. Be 'Niiiiiice' and Tell the 'Truthiness'

Fictional characters were more peaceful in '06. “Borat" tried to be “Niiiiiice,” and political satirist Stephen Colbert of Comedy Central's "The Colbert Report" promised "truthiness," or "truth that comes from the gut, not books."

1. And the winners are ...

But aside from pantyless celebrities, the pop culture phenomenon of 2006 really happened on the Internet, where "user-generated content" dominated sites like YouTube (bought by Google for $1.65 billion) and people watched Webisodes of their favorite shows when they weren't frequenting the blogosphere or playing with their Wii.

Here’s hoping that stars keep their undies on in 2007!
