The Dee Zee 

When your having drinks with your mates and one person grabs the beer box, slaps it on the ground (indoors) infront of everyone, pulls down his pants (or hers) and slops out a mass mud monkey for the rest to see. The person will then run to the toilet to clean up, usually leaving a bread crum trail.

Daniel called us all over and gave us 'The Dee Zee' last night... It was stanky!!

Deezee Day

A day when everything is hectic and goes wrong, when your coffee spills, your boss tells you to stay overtime, your teacher gives you extra homework or you fail a test and you feel anxious.

Person 1: Hi how's it going?
Person 2: shit not so good this day is crazy..Ugh!

Person 1: having a Deezee Day I see.
Person 2: yeah man everything is going wrong, I'm done with this.

Deezee 

Referring to the letter 'D' of the alphabet, in which case it is used as a common noun (a person, place or thing)
In other instances, as in the sentences below, 'deezee' is, and may commonly be, used with other words as an adjective (or a set of words that further clarifies/ describes a noun) Since the example below shows the defined word used in a sentence to further clarify/describe the common noun, bra size, the word 'deezee' is used as an adjective. Deezee, which refers to the cup size D, is used with the numerical slang 'trip', which further clarifies/describes the noun in question, and indicates that the (very expensive) bra size discussed in the example below is a triple D.

Wow that is a huge bra! What size do you wear?
Oh, my bra size? Trip deezee.
