Pronounced "Zim-Bob-Wade". Like the
past tense of "Zimbabwe", if it were a verb (which in this case, it is!)
Definition: Left quickly. Got the hell out.
(To Zimbabwe): to flee, run, escape, disappear.
It is usually meant to convey the point that this person has fled or vanished, with no warning, to a far away place, & probably doesn't want to be found.
