A unit of measurement consisting of the product of meters cubed and kilograms, divided by seconds raised to the fourth power.


The McFly is based on multiplying 88 Miles Per Hour by 1.21 gigawatts, as described in Back the the Future.
Driving at 88 miles per hour and receiving 1.21 gigawatts from a bolt of lightning gives you 47,600,000,000 McFlys, or 47,600,000 kiloMcFlys, or 47,600 megaMcFlys, or 47.6 gigaMcFlys.

a POP band. they even say themselves.
'the words rock and mcfly should never be used in the same sentence together'- QUOTE tom mcfly

yes, alot of the fans are younger girls.
but im sure they would rather have those kinda fans then 'hard' rockers who have long greasy hair and never get girls, who idolise people afriad to show there face so wear a mask.

mcfly fan: urmm whatever suits you.

An amazing band that is often called crap cause they are boys in a POP band. They are boys in a band but aren't half of the band out there boys in a band, why arent they boyband? Cause the don't play pop? Oh.. now I get it.
Quoted by Tom The fat one that aint fat anymore: We are a POP band, people always say that we are wannabe rock or punk/rock band but we are not, we are pop!
Likes of Simple Plan&Good Charlotte&Green Day&Blink 182 have said they liked them. *Shoves hand in your face and shouts 'FACE'*
And sure Busted&McFly DID sound the same.. why? THEY OFTEN WROTE THEIR SONGS TOGETHER! I have seen them live and they were amazing... just watch their tour DVD and be *Puts on Star Wars like voice* CONVINCED!
And to the ones that say they are 'Un-attractive* Can I feel.. a bit of jealousy? I think I can *Feels it* Hell yeah I can.
To be really original;
They are better than YOU!
Guy one: Gee, lyk omgz I like System of a down&Korn they are way better than McFly
Guy two: *Kills guy one* =]
Be afraid, be very afraid....

pretty much the best band on the face of the earth. whose fanbase consists of teenagers to younger kids to, older people who enjoy the remakes of older songs, and the collaboration of classic rock with new voice. They are four amazingly hot and talented guys who know how to make music.

Danny Alan David Jones-lead guitar and vocals. he has brown hair that used to be straightened, but is now is left naturally curly. he has blue eyes and freckles. his hometown is bolton, and he loves the who. he is also the biggeset fan of 'the boss', bruce springsteen.

Dougie Lee Poynter- bass guitar and backup vocals, and some solo songs like the ones he has written, transylvania, and ignorance. he currently has dirty blondish hair. he loves and is inspried by blink 182. he has numerous sparkly light up basses and bright blue eyes. one of his favorite brands is etnies, and he is the youngest of the group.(20)

Tom Michael Fletcher- rythm guitar and vocals. he normally has bleach blond hair. he has brown eyes. like dougie, he likes to wear long socks with long shorts. he has one distinct dimple on his left cheek. his car is a light blue mini cooper s. he loves the beach boys, the beatles, and green day.

Harry Mark Christopher Judd- drummer. he has brown hair and gorgeous blue eyes. he's the only guy in the world that can pull off a mullet with no effort. he's very good at cricket and is the oldest of the band.

Now, not only are these four guys incredibly hot, theyr also incredibly talented. for every person who claims that they mime playing guitars, your very very wrong. they hav never mimed guitar playing ever since they started the career. at first, i actually did think that they ddnt play for real, because all of ther performances ddnt sound out of time or out of key, and most bands, even ones i like, happen to suck live. but them...they proved me wrong, i found out that they never mime guitar playing, which rele impressed me that they can sound so perfect all the time. also people say that they are copying busted. the thing is, charlie simpson of busted went to the same school, as Harry Judd from mcfly. as well as, matt willis and tom fletcher both attending sylvia young theatre school. on top of all this, tom tried out for busted and ddnt make it, but became very close friends with james elliot bourne. james has helped him, and to this day, still does, and did with mcfly's new album coming out july 14th. he helps write songs and find melodies. so in a sense, and mcfly has admitted to it, busted definately helped start them off on their big breakthrough by letting mcfly tour with them at the peak of their own career. sure the music they made may seem similar in a sense, but still will never be the same. all in all, mcfly are extremely amazing, and unless you dont like them because u dont enjoy ther music, you hate them because your jealous.. and thats completely believable :]
They got their name from Marty Mcfly of back to the future.
