= Personal magnetism
Mojo will make one seem and feel sexy, virile, appealing, invincible and in control etc.
Alcohol or love usually awakes the mojo.
When ones mojo is working, it often results in flirting and heavy socializing with the opposite sex (or whatever prefered).
That quality, often elusive, that sets a person apart from everyone else. The word "magic" could, almost without exception, replace "mojo" it in all of its contexts, sentences, and/or applications.
I just saw David Lee Roth on Leno last night. He was doing old Van Halen songs though with a Country feel ... he has DEFINITELY his mojo!!
