look up any word, like blumpkin:
(verb) To masturbate under a desk or table during class.

Only applies to men masturbating as "craig" is a masculine verb. Only masturbating under a desk or table does not constitute as craiging, the deed must occur in a classroom during a lecture or other educational lesson.

Origin: From the Celtic name "Craig" transformed through anthimeria from a noun into a verb because of a dumbass of the same name performing said act.
"Hey, did you hear about that kid in Mr. Witt's class?"
"Craig? Masturbating? Yeah I heard."
"He was totally craiging!"

"Did you see our substitute teacher's cleavage?"
"Yeah, I'm totally going to craig to that"
"Great idea man, pass the hand lotion."

A move in the school lunch line where one or a small group of people sneak into the door where the people who have already gotten their lunch come out; attempting to get your lunch earlier; without getting caught.
Me: "look, Brittany and Brenna are attempting to pull a Craig!!"
Rachel: "They have balls."
