shoulder-dicking 

The act of placing your exposed penis on someone's shoulder without their consent or prior knowledge.

Did you see the new receptionist? I would totally shoulder-dick her.
I heard Alan got fired for shoulder-dicking the new receptionist.

Shoulder-Dicking 

When you're seated next to someone who has a standing desk, creating the awkward situation of having their dick at your shoulder height.

Brad is great, but honestly ever since he got a standing-desk I feel like he's shoulder-dicking me all the time. Every time I turn around his dick is right there on my shoulder.
