To puke from drinking too much. Other drugs may be involved but it is a strictly alcohol
based stunt.
It is an act that should be embraced totally and appreciated by all. If it is only a mild fettle, as in you puke a little but don't mong, then it is recomended you keep on drinking.
In the event of someone fettling, it is a courtesy to then sing "For he's a jolly good fettle" to the tune of "He's a jolly good fellow."
Fettles usually lead to hard monging, passing out and periods of forgetfulness and general confusion.
Fettles aproach differently for different
people.
Some come sudden and unexpected, most ammusing if a person has to improvise what they
will fettle into. Favourate choices for these are sinks or buckets.
However, the worst kind of fettle
will start with a simple queazy feeling in your stomache. The feeling
will grow and before too long it
will be
time and you
will know when it is time.
If
people are not too drunk to move at this stage they
will usually make a crawl for an out door spot out of the path or more traditionally a toilet.
When outdoors, bushes, bridges and rivers, for the daring, are good choices for fettle spots, however this choice lacks a
mark that would be made by a straight out fettle in a public place that you would later be able to look at and say "I did that"
The effects of fettling whilst not being able to move are disasterous.
Don't let
people pass out in sacred rooms if you fear a fettle. Move them outside, to a toilet or stick them in a bath to bathe in their own filth, those bastads.
In extreme cases, be willing to
run ahead of fettlers as they may be lacking the ability to lift toilet seats and open doors.
