Russian Blue 

A sex act involving a sexually frustrated man who has been teased for a justified amount of time (with blue balls) & a bottle of vodka.

Vodka is poured liberally on the balls with the woman sucking & licking the vodka off.

Once the man has released his frustration the pair rinse off in the shower before engaging in intercourse in whatever style takes their fancy.

This act works best between a couple from two different continents.

Adam: "I love you. Take me home & give me a Russian Blue"

How Blue Can You Get 

Standard blues song popularized by B.B. King. Has the following verse in it that everybody knows. (Anybody who has been listening to blues and knows their Mojo from their Baby, also please note that the song was performed most frequently in the 50s, when a 10 dollar dinner was pretty expensive)

"I gave you a brand new ford, you said 'I want a Cadillac.'
I bought you a ten dollar dinner, you said 'thanks for the snack'
I let you live in my penhouse, you said it was just a shack.
I gave you seven children, and now you wanna give 'em back! Oh how blue can you get?"

"How Blue can you Get" is perhaps B.B. Kings best work.

Little Blue Box

the "Little Blue Box" is used to refer to the TARDIS, the Doctor's time-traveling spaceship in the BBC show "Doctor Who". The show, the longest running television show, is one of the most popular shows in the United Kingdom, and is also popular world wide. TARDIS, or Time And Relative Dimensions In Space, is how the Doctor is able to travel through the universe. To people who do not know of the Doctor and see TARDIS, since it is disguised as a police box, call it a "little blue box".

Donna: You really believe in all that stuff, don't you?
Grand dad: It's all over the place these days. If I wait here long enough . . .
Donna: I don't suppose you've seen a little blue box?
Grand dad: Is that slang for something?
Donna: No, I mean it. If you ever see a little blue box flying out there in the sky, you shout for me Gramps. Oh, you just shout.
