look up any word, like wyd:
 
1.
Two month period of January and February where ladies are generally easier to obtain due to having been dumped just after Christmas (after their boyfiend has had their presents), and they can't cope the Valentine's period without having a boyfriend.
"I can't believe he dumped Rachel after she bought him an iPhone for Christmas."

"I don't care - it's Fannyuary, so she'll be easy. Maybe I'll dump her, too. The day before Valentine's Day, so I don't have to buy her a present."

Mark's favourite time of the year is Fannyuary when all the girls are on the rebound, and he can get some pussy.
