CFT- maybe I can help you remember let's see- Om is the sound many people make when they meditate. "Kiri" kinda sounds like the sound a crow makes and "swaha" kinda sounds like "swallow".
Now picture in your mind a very weird scenario- the weirder the scenerio the better one remembers.
Picture yourself meditating and while meditating- humming "ommm..." suddenly- the image of a crow appears in your mind and he goes "kiri, kiri..." you're so startled you have to wake up fast and go eat some comfort food- and so you swallow ("swaha") a big, fat cookie!
