Hey Denzel, have you heard that Marlo took Camilla back after all that bullshit? She got 3 kids with the other dude she left M for and now she talking about it was a mistake. The sucka took her back, smh.

Denzel: That shit is straight birdery. The fuck is Marlo thinking?

Ex 2: Denzel: Juan Jose said Jayla keeps hitting his line, talking about, this some true love shit, now that he hit a lick and stacked up nicely.

Rayshawn: I ain't surprised. Typical birdery shit right there. Good thing he ain't a sucka and won't end up being her lick that she makes a come up on. Where was she before? She wasn't in the trenches, she wasn't shooting in the gym.

Example 3: Rayshawn: Yo Denzel, Ashlin filed for divorce from Darien.

Denzel: I told dude not to marry that thot. She been a bird, we all knew that. I don't feel bad for the guy. Dudes who are dumb enough to marry hoes, deserve what comes with that. He deserves that misery for allowing himself to succumb to her birdery.

Birderer 

Anyone who kills a bird whether intentionally or otherwise. For example; a friend of mine hit a bird today.. and instead of calling her a "bird murderer" in the text that I was typing to her, I consolidated and threw "birderer" at her. I actually think it cheered her bird-killing self up a bit.
girl driving car: oh crap i think i just hit that bird
guy passenger: wow it's not moving, I think you killed it... YOU BIRDERER

A birder is a lad who laps up attention off the ladies and thinks of themselves as pretty much a big deal. Probably quite good looking, but more importantly, thinks that they're the fittest thing to ever walk the earth.

Birders will always have several girls on the go, and probably have different names for all of them. E.g 'wifey', 'baby girl' or 'boo' - this keeps all the women feeling special and thinking that they're the only 1
Girl 1: "Hey, u heard of that josh evans?he seems pretty cool"
Girl 2: "Yeah- a big time birder, don't go there babe"

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
