Pika = Electric
Chu = Mouse

1. Pikachu is an electric mouse found in the games, tv show, and movies of Pokemon.

2. The very reason why the show Pokemon shouldn't be aired anymore, in english... edited... Because the show has been KIDDYORIZED to attract small children, instead of the intended audiences of Early teens.
I really hate that Pikachu.
Pikachu, GO!
Oh yes Pikachu, harder!
That damn Pikachu shocked the hell out of me!

Just like other japanese pokemon names, the word Pikachu has a childish meaning from onomatopeic expressions such as girigiri and pikapika. Pika is taken from the sound of sparks or the effect of something being shiny. Chu is the sound a mouse makes as well as a kiss. Easy for children to remember and understand. Pikachu is an electric mouse pokemon, although he looks like a rabbit squirrel tiger with cockatiel cheeks. He popularized pokemon and is the main mascot of the show in the united states. Much more popular now that in japan as now japan has been taken over by battle beatles. Some people want him to die and some want to make love to him. I thought he was cute when I was 12.
Pikachu fainted. Let's eat him.

1. An electric mouse pokémon. Many of them gather in electrical storms. It has small pouches on its cheeks that discharge electricity. (from the pokédex)

2. A cute, small pokémon that was crossed between a lightning bolt and a mouse. If you grab one's tail, it'll shock the pants off ya.

3. See pokemon, pokémon, pocket monsters, or electrical mouse.

A misunderstood yellow rat-like creature that often shows up on the show pokemon. We can all agree that if he wasn't portrayed in a manner that looked like a 4-year old's imagination and if people could actually understand what he was saying, his cool points would total around that of Nickelback. His abilities include emitting powerful electric shocks. Recenlty he has attempeted to get his name changed to Brandon.
"Pika Pika!"

"Pikachu says that he hates the director of pokemon and would like to take a shotgun to his head."

While it is an adorable yellow creature, when referred to by Chelsea Handler, it refers to a woman's pussy.
Brittany Spears's pikachu is all over the internet because she doesn't wear any panties.
