One who has an over the top or abnormal obsession and infatuation with the famous British rock group called the Beatles
Christina, who owned every Beatles record and knew every song they had ever written, was considered by all who knew her to be a real beatlemaniac.
People with an obsession with The Beatles. They're also the greatest group of fans in the world.
"wow that girl is awesome"
"she's a beatlemaniac"
"LET ME MARRY HER"
Someone who's life solely relates to the obsession and collection of beatle's paraphernalia.
'i want that platinum 1964's gold crested beatle's poster! it's only 900.00!!!'
'dude, you're a total beatle maniac!'
The biggest proactive fan of popular british band The Beatles, who only like bands and don't say negative things about other bands. Can easily leave bisexual Directioners or faggy Beliebers behind. Know what great music actually is, and for that matter have a very good taste in music. Possibly the awesomest fandoms ever to roam the Earth.
Gal1: Dude, I am starting to like The Beatle
Guy2: I think you're becoming a Beatlemaniac.
Gal1: Is that good?
Guy2: Damn right it is. *croutches* I love the Beatles, and so do you. Will you marry me?
