sin master 

Another colorful way to describe the male member; in some instances, quite eloquently.

I introduced her to my sin master last night

SilMaster

Short for the two words "Silly Master." Or, depending on how you use it, it can mean Silly Masturbater. Mostly used while texting.

Ex 1:
"Laughing my fucking ass off, you're a silmaster at this game."

Ex 2: (Said by an Australian, or a British person.)
"Oi, get oveh he'e ye silmasta'"
