look up any word, like cunt:
 
1.
An exclamation sounded, triumphantly, when one produces both a fart and a burp either concurrently (a true kushtumpah, and worthy the name) or within a very short space of time (a weak, or 'feminine' kushtumpah). To qualify as a kushtumpah, both the burp and the fart must be done by ONE PARTY ONLY and must occur within no more than three seconds of one another.
*burp* ... *fart* ... "Kushtumpah!"
