A person who tries to play bball but really has some serious misunderstandings about certain technicalities such "travelling". Hence, even though they keep playing thinking that they're not travelling, they must be imagining that they are dribbling the ball...hence the term "invisible dribble".
Could also be applied to people who think they have any kind of game, not just in bball...life in general.
Situation 1 - Playing Ball
Dude 1 - "Dude, look at all those steps he's taking...he's doing the carlton and he doesn't even know it. Doesn't he know he has to dribble the ball?"
Dude 2 - "Yeah, he's got mad inivisible dribble skills".
Situation 2 - Picking up a chick
"Check out that dude over there trying to work some game on that chick...he's got nothing man...no response...nada...seriously - invisible dribble and a half. But damn, she is who-licious nonetheless."
