Firday is a term used for describing the hindmost weekday of every week, wherein interested parties pay their respect to pine trees - most notably the Balsam and Fraser Fir. Bekka is also wrong, but I digress.
Me - "Man, so keen to get my Firday celebrations underway!"
Bekka - "L0L UR DUM ITZ 'FRIDAY'."
Me - "Have some respect for Balsam the Almighty, you heathen scum!"
