«زَيِّ بَرَاغِيتِ الْوِكَالَةْ يُحُطُّوا الرَّك عَلَى الْبَيَّاتَهْ»

The saying pictures fleas in a wakāla, here a shabby lodging house for the poor rather than an agency. They have no host of their own and simply wait for each night's sleepers to arrive, then live off them. The image presents dependence on transient strangers as the whole basis of one's survival.

Applied to people, it ridicules anyone who sponges on outsiders, guests, or passers-by rather than supporting themselves. The jab suggests opportunism: such people attach themselves to whoever is newly available, take what they can, and treat each new arrival as their next source of sustenance.

Said mockingly of people who make no living of their own and instead feed off whoever happens to pass through, such as newcomers, guests, or temporary visitors. Because it likens the target to vermin, it is insulting when aimed at someone directly and suits sharp criticism, not polite talk.
