(n) A person who is your best friend and you and everyone else finds him or her very attractive and or sexy and they are ignorant to this beauty. This attractiveness is not bias and is not derived from the fact that they are your best friend. They have just kind of grown out of awkwardness and stumbled into beautiful perfection.

Often hailed as one of the top rock acts to come from Scotland in recent years, been on the underground radar for most of their career & still to this year (early 2011) are quite unknown despite working their arses off.
Achieved moderate commercial fame from the use of their song ''many of Horror'' being covered by X-Factor winner matt cardle.
Most notable for their time signatures, energetic gigs, Simons screams as he smashes his strings on his guitar during heavier songs, playing topless, thick scottish accents & being very crowd friendly + Simon their singer at times sounding quite like Cobain & Grohl (see ''eradicate the doubt'')
Genre: alt-rock/hardcore/indie
Fan chant: MON THE BIFF

Annoying ''real'' Biffy fans often split the band into ''old biffy & new biffy'' where the latest two Biffy albums (Puzzle & Only revolutions) are seen as new biffy due to their change in record company & apparently a change in their overall sound.

''Theres No Such Thing As A Jaggy Snake'' is often seen as the core song to summarise Biffys music as it contains all of their trademarks. ''Bodies In Flight'' in my opinion is another good track to summarise the bands style
Annoying Indie biffy fan: Man Biffy Clyro suck now, only revolutions was so commercial. They have sold-out & changed their sound, ah the good old days of Infinity Land i wish they still made music like that

Die hard biffy fan: Firstly shut the fuck up & secondly I beg to differ the likes of ''Get Fucked Stud/That Golden Rule/Livings A Problem/Cloud Of Stink/Help Me Be Captain'' are still very similar in style to Biffys earlier albums which were gritty rock.
A band doesn't owe it to you to keep pumping out the same type album for their entire career, off with you & go listen to Oasis if thats what you're after & be happy that Biffy produced something you enjoyed.
