Duration: It starts the day after Halloween and ends the day after Valentine's Day.
November 1st - February 15th
When done with ulterior motives, it's the time women trick desperate men with romantic inclinations to get gifts and guys 'date down' to get gifts from desperate, grateful low hanging fruit.
It's a despicable practice and I don't suggest anyone doing the aforementioned, especially since during this time of year, emotions are extremely high and you risk getting your tires slashed (men).
But when it's mutual and both parties are knowledgeable and complicit in the act, it can be worthwhile; they just want to spend the cold holidays with someone who cares for them (even if it's just an illusion of a relationship OR 'seasonal friends with benefits
The reason behind this is that in most places it's cold and cloudy most of the time; a very depressing time of the year for most, but even more so when you don't have someone who cares for you or willing to spend time with you.
Some ladies with means/looks get boy toys
and some guys opt out of a serious relationship for 'girlfriend experience'.
Those who were in lasting relationships before cuffing season...well, there's a reason why the majority of children are born in August - October...they were conceived...IN CUFFING SEASON!
