hiccup burp 

noise made when a person tries to suppress a hiccup and ends up burping that the same time, resulting in a loud abnormal sound

my sister tried to stop her hiccup and ending up doing a hiccup burp.

This is the action in witch you attempt to burp but then you instantaneously hiccup at the exact moment.
