jack-a-leg

A total, complete doofus who just can't seem to get anything right, ever. Can also be used to refer to an animal, such as a dog, who acts totally off-the-wall, unpredictable and sometimes anti-social.

That goddam black catahoula just went after my neighbor's friendly dog. She can be such a jack-a-leg sometimes.

A perversion of the children noise of a chicken, cock a doodle doo. Cock is itself a slang word meaning penis. Thus Jack would be an action to the penis as to Jack Off. Doodle is a slang for sex. Thus meaning a action of sexual pleasure with out intercourse. To Jack off is done alone. Jack a Doodle Doo would be done by two persons to obtain sexual pleasure. The analogy of going to 3rd base.

Larry and Michelle do not go all the way, they just Jack a Doodle Doo.
