the act of guys taking a crap on the toilet and jacking off
Dude, he's taking so long in the bathroom, do you think he's crapjacking?

Get the crapjack mug.
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."

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.
