The act of leaving or finishing early. This term is always a negative.
Examples: A teacher dismissing class before the bell rings, stepping and falling out of an airplane doorway before the steps have been deployed, or pre-mature ejaculation. "I was with this chick last night and pulled a hanshaw." "In third period today my teacher pulled a hanshaw." "I flew to Greece and this idiot pulled a hanshaw."
