Also sometimes written as Gash Monte-Rouge
'Gashmont' - An extention of 'Gash'. A thing or person considered to be rubbish.
The lowest of the low.
Worse then being simply gash (ie. Sub-Gash)
'Rouge' - French origin meaning 'Red'.
The exact reason why Rouge should follow the word Gashmont is still unknown.
Not to be confused with a Gashmont-rogue, someone who is not only gash but also a scoundrel.
