Friend: did you watch dd yet?
You: yes! I also came!

The greatest people you will ever meet.
Originally from Detroit & a lover of One Direction
"Hey, did you meet those DD's?" "Yeah, they're great!"
In Swedish it means "du då". Which is translated to "you then" or most commonly "and you". You usually write a question mark afterwards.
Theo: How are you?
Me: I'm fine, dd?
DD stands for dad's dad. It is for the grandfathers biologically that aren't comfortable with the notion and image they grew up with of a kid calling said human, gramps, grampa or anything so-not-cool that they latch onto the much cooler sounding DD.
Who's this?
DD. My dad's dad. The coolest grandfather on the planet. When the grandfather image don't fit, you must acquit.
