D:

A distressed emoticon. Partially translatable as "Oh No!"

An emoticon that conveys deep and extreme distress. This is obvious when you look at it and see how freakin' sad it looks.

Can only be used in the immediate aftermath of or during someone sleeping with your wife.

An emoticon often used to connotate a silly or comedic form of shock or surprise, but often used in situations that don't necessarily mean shock or surprise.

The most commonly used drive letter for a CD-ROM drive.

A designation for a letter drive on a computer, as in a hard drive, hard drive partition, CD-ROM drive, etc.

Generally, because A: is reserved for a 3 1/2 inch floppy drive, B: for the obsolete 5 1/4 floppy drive (the letter is skipped if the drive does not exist), and C: for the first hard drive, D: is most often a second hard drive or a first CD-ROM drive.

Letters thereafter, such as E:, F:, G:, etc. can be filled by CD-ROM drives, burners, external hard drives, USB drives, and the like as necessary. While not required to be in alphabetical order, it is this way by default.
