cramjack 

its a device worn between two males having sex. it is worn by both males at the same time. it is worn over both penises. every time the man in the back thrusts, it jacks off the guy taking it in the butt. basically eliminates the reach-around procedure.

i just bought a new cramjack ...yay!!

crapjack 

When you masterbate in a bathroom and then crap so you can tell people you were crapping.

"What were you doing in there?"
"Just going poop."
"You were probably taking a crapjack."

Crapjacked 

Someone stole (jacked) your stuff (crap)

Me and my friends walked over to the lunch lines, leaving are backpacks unattended. We came back to find that both of our wallets were missing. We just got crapjacked.
