«اِلْغَاوِي يِنَقَّطْ بِطَاقِيِّتُهْ»

The picture is a wedding guest so fond of the singing that, finding his pockets empty, he hands over the small skullcap from his own head as his cash gift to the singer, a modest possession given because nothing else is at hand. His enthusiasm will not let a lack of money stop him.

The figure is the passionate devotee, not a seducer or someone gone astray. Applied broadly, the saying describes enthusiasts of any pursuit who pour into it everything available, whether trivial or valuable, noting with amusement and understanding that real passion finds some way to give.

Say it with affectionate irony about someone whose hobby or passion makes them give whatever they have, cheap or precious, as when a collector or fan spends beyond their means. It suits light teasing or admiring comment rather than harsh criticism.
