bo xì

Verb

 * 1)  to stop hanging out with; to not play with anymore

Usage notes

 * When bo xì someone, a child would also often do the action of covering and uncovering their mouth during the duration of the lengthened bo (somewhat similar to the stereotypical "Native American war-cry"), and just after xì is pronounced, finishes it by throwing their hand toward the other child with whom they just denounce their "playmateship".
