A date that doesn't exist and never will. So if home boy decides the date you're planning to have is in February 31st then you clearly know hes mocking you. So basically you'll never be able to go out with him or her.

Get a February 31 mug for your dog Abdul.
The day that comes once a year where you can masterbait at school and fuck people in corners. It's like the purge but sexual laws are the only ones that are legal for 24 hours.

On this day you can fuck your family and get 8 women pregnant.

It is also a day of exploring. You can try fucking different ages, sexs, or cultures.
