bird migration

"Strangelation, altercation,
Oral sex and bird migration"

Little Johnny was just as frieghtened as the Milermore Bird as the loud screech pierced his ears.

Dirty Bird

'A girl who usually appears innocent, often having a private school background, but who is ultimately ten times dirtier than any other girl out there. She revels in being a sort of 'secret slut' and only very few know about her slutty behaviour. She enjoys most sexually activities, especially those that others find out of bounds and has most likely engaged in sex with multiple men. In short, she is filthy.'

'That girl Zoe is a right dirty bird, last night she came round to my house and sucked off me and my best mate before letting us both take her from behind'

Song Bird

A song bird is an entirely white bird known for its disctinct voice, "singing," during the breeding season. A song bird is different than any other bird because it is the females who looked for their mates and sing the tunes that make the males fly for miles to mate. For the urbanites, A song bird is any hot chick whose slightest whisper can make guys go berserk to get a glimpse of her.

Dude 1: Dude! She's laughing.
Dude 2: Who?
Dude 1: The girl next door
Dude 2: WTF! You can hear her from here?
Dude 1: She's a song bird
