સારા જાણી નેતરી, ગધેડાની સાથે જેતર્યા, ને ભાણે બેસી મુતર્યા.

sārā jāṇī nētarī, gadhēḍānī sāthē jētaryā, nē bhāṇē bēsī mutaryā.

Literally: Invited considering them good, yoked them with donkeys, and they urinated sitting at the dinner plate.
What it means: Repaying hospitality and respect with coarse, disgraceful behavior.
