A fake holiday.
Valentine's Day is a fauxliday designed to waste your money and time on gifts, when you could be wasting it on beer and getting laid, respectively.
A) On vacation (or 'holiday', as they say in the UK) while mentally and/or physically distracted by the worries of everyday life
B) an apparently bright & beautiful vacation suddenly ruined by unexpectedly inclement weather.
C) a religious holiday celebrated by non-adherants of said religion
(i.e. Muslim celebrating Yom Kippur
or an atheist celebrating Christmas)
"I went with me mum on holiday, but it rained consantly so we stayed indoors. What a fauxliday!"
