look up any word, like half chub:
a group made up of four strapping young lads (with flippin sexy voices) who have 7 number one's under their belt, a world record and 3 wicked tours, 3 albums and two DVD's.

McFly are a fantastic british pop band and have a large following of young female fans, not sweaty fat men like the rock scene so thoroughly enjoy.

They regularly receive underwear and get boobs flashed at them thanks to their musical talent, good looks and all round fantasticness.

Generally, Mcfly are much better than you and unlike Mark from blink, dougie has good hair AND Tom is no longer fat thanks :)

you all suck cock.
Artard: McFly are so shit. all their fans are teenage girls!

Me: Yeh, i bet that sucks. i'd much rather have sweaty fat men shouting at me and jumping on me than fit birds showing me their massive boobs. that would make me vomit.

Good person: I love McFly, they're talented and inspirational. they should really be alot more wolrd wide known than they are, alough they already are popular throught the world
Me: Well done! I like you! Haha

The worst band in existence ever!
