An even more devastating insult based on 'ur mum gay'. It's so destructive and intellectually stimulating, apply with caution.

Get the Ur mum public good mug.Used as a term to express frustration, annoyance or mild anger at something, somewhat similar to "For Fuck Sake". Can also be abbreviated in short messages in a similar way and it is not uncommon to see the acronym CKFM. When pronouncing, the emphasis is placed on the word 'fucking'.
The Phrase originated in Cranbourne School, Basingstoke (UK) in the mid 1990's where Clive Kents mum would give gob jobs to the boys for a can of Strongbow cider. Since then the phrase has spread and entered the lexicon of most of Hampshire (UK) and has also spread to areas of Leicester and Leicestershire (UK).
