To relax but in an entirely unproductive manner. Essentially sit in you own filth and do nothing useful.

Mongout 

One of many types of weed available for purchase in your local community. Mongout is a word that can describe any weed that hits you straight away (rather than sneaking up on you) and puts you in a state of complete haze

Clive: I'm guessing it's Mongout then
