Flatigued; verb, in a state of being flatigued.
The word deriving from combination of two words or the art of portmanteau, was soon seen popularly used (sometimes practically) in the area it originated from, namely PafuriZA’s room.
The word means to be in such a state of tiredness or utter exhaustion that the person with flatigue would fall asleep whenever they reach a horizontal position due to purposefully laying down or falling over due to exhaustion.
It has been noted in some cases that a person can experience flatigue while still vertical, which then on experience would result in the immediate termination of that stance towards a more natural flatigued position.
ps: Why don’t you make up your own word as well? It’s more fun than you might think.
