The most beautiful woman to walk the planet. Although she lacks talent she makes up for it in personality and looks.
Guy: "Look! Katy Perry's on SNL!"

Guy 2: "I hope she doesn't sing."

Guy: "Who cares?! She's Beautiful!"

Get the Katy Perry mug.
A popular female singer who makes horrible, ear-piercing songs. The one and only reason why anyone likes her is because of her enormous boobs and her hot ass. The only reason guys buy her albums is because it will give her reasons to perform on stage and dance around half-naked so we can jerk off to her.
That girl only has a 100 in math because she fucks the teacher. What a Katy Perry.

Katy Perry (aka Kathryn Hudson, Katy Hudson) is a American singer/songwriter from California.

She first got noticed when Madonna named her single "Ur So Gay" the song of summer in 2007.

She then blew up with her hit singles, "I Kissed A Girl", "Hot N Cold", and "Waking Up In Vegas" off her debut album "One Of The Boys".

She followed "One Of The Boys" with "Katy Perry Unplugged" and will soon release her second full studio album "Teenage Dream" in August of 2010.

A little known fact about Katy Perry is that she recorded an album for Columbia records in 2005 that was never released. Many of the songs Katy wrote for this album were later recorded by Kelly Clarkson such as "Longshot".
Did you hear the new Katy Perry song "California Gurls"? It's so great.

Get the Katy Perry mug.
The art of listening or watching, memorising Katy Perry performances, videos and lyrics.

This could be in an obsessive fashion, or hardcore girl fan style.

This could also mean someone who is completely obsessed or deluded with Katy Perry in every way and is constantly needing to get their 'KP' fix, this is known as Katy Perrying.
Person 1: "Hey dude, wanna hang out today?"
Person 2: "No sorry, I'm Katy Perrying all day"
Person 1: "WTF, that stupid bitch who can't sing and has big tits?"
Person 2: "STFU.... *starts crying*

Get the Katy Perrying mug.
A two-faced bitch who, while she does make some catchy songs, is still extremely untalented. She is also apparently a sore loser, as she dedicated her song "You're So Gay!" to the German emo boy-band Tokio Hotel who beat her to the VMA's "Best New Artist of the Year"
Person 1: Did you hear about what Katy Perry did after the VMA awards?

Person 2: No. What did she do?

Person 1: Well this random German emo boy-band called Tokio Hotel won "Best New Artist of the Year" Award and apparently Katy Perry wasn't happy about.

Person 2: Why? What did she do to them?

Person 1: She wanted to win that award. However she didn't so she decided to slander them by dedicating her song "You're So Gay" to them.

Person 2: Wow what a bitch.

Person 1: Yeah I feel sorry for Tokio Hotel, they already have enough people who think they're gay just because the lead singer looks likes a transgender. The last thing they needed was for Katy Perry to slander them.
