Yo are you free this weekend, I was thinking we could go do some Slovakian munging

Monging Out 

Basically - Zoning out, going into a daydream like state and you can't help but do so. When your eyes become fuzzy and you love to stare at an object in front of your eyes.

It's both a natural thing that happens and can also be caused by smoking weed.

"I can't stop monging out!"
