"What the dog doin'?" It's an internet meme that became popular again.
Friend: *walking his dog*
Me: "What the dog doing?"

Friend: *sends snap of his/her dog*
Me: "Wtdd?"

Short for “What That Dick Do?!” This is a question you ask your bestie when she finds a new guy. Generally asked early on when they first meet and they havent been engaged sexually yet so the jury is still out. Used great as a mantra to get pumped up before going out! It can also be asked aggressively when you really want to find out WTDD? and the anticipation is growing strong and/or that dick didnt do shit. Truly we still dont know...
“Lets go out in Manayunk tonight, the dude I met in Miami Is coming” “O shit! Roberto?! Yoo WTDD?!”
