look up any word, like dirty sanchez:
 
1.
The practise of smoking cannabis through a bong while under the influence of ketamine.

This is a rather intense high, somewhat psychedelic, and sometimes even enjoyable.
The name is a bastardisation of the term Bong Mix, re-arranged so because this activity is known to cause severe episodes of monging out completely.
Bonging and snorting Ketamine together is called Mong Bix, and its fucking intense.
