To crank is to wank and cry simultaneously. The tears can be used as lubricant. Cranking is most commonly done when a relationship has just ended.
"I had a crank two hours ago" "My boyfriend just dumped me, I really need a crank" "I saw you cranking last night" "You're a cranker" "Your mum just caught me cranking" "Don't sit on that sofa, I had a drunken crank there when I got back last night"
