This word can be used to console someone who has just suffered from a severe lack of luck in an extremely important, possibly life-threatening, situation. It is particularly useful when use of the word 'unlucky' would be a flagrant understatement, while the phrase 'fucking unlucky' would just feel clumsy and out-of-place. 'F-unlucky,' in contrast, rolls off the tongue nicely and is also less likely to cause offence.
It is of utmost importance that the word 'f-unlucky' not be used in a situation when the phrase 'bad skills' is the only suitable observation. The phrases each have very different meanings and must not be confused: 'f-unlucky' suggests that the consolee did indeed have good skills, but the situation was really beyond their control.
Here are some examples of situations in which the word 'f-unlucky' would prove appropriate:
2. Upon journeying one evening, in high spirits, to The Clifton, the establishment is found to be closed "for refurbishment." It also becomes apparent that it will not be re-opening for a good six weeks: "Hmm, that's rather f-unlucky. What are we going to do now?"
3. News emerges that a friend (who, for the purposes of an example, we will refer to as Fraser) has recently been brutally and unexpectedly murdered: "Oh well, Fraser was generally pretty f-unlucky."
