short for "share my dream"... originally taken as an insult (suck my dick). Used in the bait and switch technique.

Tom: Hey Shawn, S my D

Shawn: fuck off, Tom

Tom: what??? share my dream!

Shawn: whatever, why do I always get screwed?

It's literal meaning is suck my d***, but also means f*** off, or back off.

A sign of defiance.
Hell no I'm not doing that! You can "s my d"!!

You could "s my d" before I do that.
