Gashment 

1) A place or event where "bare" (loads of) "gash" (bitches/pussy) is "drawn" (had)

2) An exclamation of delight/satisfaction/approval.

British slang, originating and communly used in the Stevenage/WGC ghettos of Herfordshire, it has multiple meanings and is used in a variety of situations.
Gashment comes from the combination of the words "Gash" meaning pussy, or bitches, and the word "Bashment" meaning a club or party, usually playing Jamaican dancehall type music.

1) "Yo that was some sick gashment we rollzed to last night."

2) "Gashment Blud!!!"

Gashmont-rouge

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.

'Have you heard that new ******* tune?'
'yea, its seriously Gashmont-rouge'

or

'Have you heard what George Bush has been up to this week?'
'No..but i think he's the biggest fucking gashmont-rouge on two legs'.
