When a girl gives two handjobs at once, while bending over, so it looks like her arms are flapping wings, while another guy pounds her from behind, making her squawk like a bird.

Dirty Bird 

A nasty, grosse, just all around disgusting woman. Most commonly refered to as a skank. A dirty bird can be found in all types of setting: office, retail, high school, college, military (most have been found here). A dirty bird usually think she is not a dirty bird or skank and always laughs when someone calls her that. In all reality the people are not joking and really do think she is a nasty piece of shit.

Also if said woman is white and likes black men, then she is one of the biggest dirty birds of all time.

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'
