The day where the living triangles destroy your home if there is an instance of 3 in there. (or just the 8th day of the week)
OH FUCK, THERE IS A 3 IN HERE AND IT'S FUCKING TRIDAY.

Get the Triday mug.
1. Same meaning as Friday just spelled as "Triday" 2. Accidentally typed in an AIM conversation as "Triday" instead of "Friday" 3. "tri" means the best time of something and Triday (Friday) is the best day of the week 4. Cinnamon Toast Crunch (thats not a definition i just felt like typing it).
