When you wake up in the middle of the night, and you have the undeniable urge to shit.
I had a big bowl of chili before I went to bed and I had a Sandman special come knockin'.
is when someone is sleeping and you squat over their neck and shit on their nose.
My girlfriend was so pissed I stayed at the bar late last night, that I woke up this morning with The Sandman Special.
Girl 1: "Girl, I'm so fucking mad at Jimmy. He came home so drunk from the bar last night he passed out on the couch. So, I gave him The Sandman Special."
Girl 2: "Fuck yes, Girl! He deserved it!"
