1. To lust for something so consummately that the quest, if successful, would result in obtaining a thing of such rare beauty, "it belongs in a museum", a la Indiana Jones often said in the classic films. To desire something painfully and immediately.
2. Acting like or imitating action/adventure hero, fictional archaeologist Indiana Jones. To be more adventurous and daring than usual.
1. "Ladies, I am Indiana Jonesin' for some poon tonight!"
2. "Man, Matt's off in his own world again, stuntin' and Indiana Jonesin' trying to impress Denise. Pfft. We all know he never gets his ass off that couch, otherwise!"
