Derived from the days of the week, it is a holiday of sorts. It takes place every last Friday of every month in which a person smokes marijuana. The celebration of said day can also depend on a persons emotional status and or accesibility to said illicit narcotics.

NOTE: May also be used with any other day of the week, and/or any Friday in the month.
Jairo B. and Izzy T. celebrate Fridank every last Friday of the month.

Izzy T. was going to work on Fridank, but realized the occasion and completely missed work for the next three weeks.
