Good In Bed
One who excels in the action of ruckus love making. (Eg. women who are paid to do so, horny italian women.)
The very deffinition is derived from one intoxicated night whilst in the company of one whome was attractive. After setting ones mind on the partner they then ensure that the other is also into the situation by engaging in "flirting". When one feels the time has come they wouldst then commence in following their basic instincts of jumping into their skivvies and sexing-it-up. But unlike any other intoxicated (or other-wise) hook up, this one particular incident with the G.I.B. would be most enjoyable, and would be remembered forever by the partner chosen on that fatefull night.
