A gesture with one's face that looks like the letter D with his/her mouth, and 8 for eyes. A very mysterious pose, not known to many.

D represents the mouth, 8 represents the bugged-out eyes.

An emoticon used to express (mostly comedic or exaggerated) agony, distress, anger, or suffering.
Usually used in chats.
A- "Hey, wanna come for the party tomorrow?"

B-"Um. I'm so sorry ): I can't go."

For one, it can be 'date' in chat speak.

Second of all, it can be a smilely with D as the mouth and 8 as the eyes. Not many people know what it means, but I believe it may be an extreme case of D:
Girl texting boy: 'hi, i lyk u! wana D8?!"
Boy: "Uh..."

Person 1: *Cough cough* I'm dying... x_x
Person 2: No!! D8 Don't die!!
