A person who likes to do the same things year after year.
I set up a “LOVE YA TABLE” in my kitchen on Valentine’s Day. I plant my annual flowers and vegetables in the spring. I decorate my house for Halloween. I carve a pumpkin and give out yummy treats. In November, I put my garden to bed for the winter. Then I ski as much as I can all winter, right into April. I have a perennial personality as I do the same thing year after year after year.
The Perennial Blast is the name given to a bowling stike where the ball hits 5 pins, specifically the 1,3,5,8, and 9 pins by itself for a right hander (the 1,2,5,8,and 9 for a left hander). The result is the complete and utter destruction of the pin deck. It is a feat so awesome the sound can be heard from outside the bowling establishment in and or beyond the parking lot. Perennial blast strikes are often registered on the richter scale.
(Joe) "WHOA! What da hell was dat sound!! We're at the bowling alley under attack!!" "I thought the war was over." (Mike) "Chillcuz. Dude struck again." (Joe) "Damn!" (Mike) "I know, it was just perennial blast!"
The moment in time when life was created. Everything that lives has a beginning, an origin in time that caused it to grow and develop into all organic life we have today. The slice of time when organic life began is known as the Pirenium.
NOTE: there is a closely spelled medical term known as the Perineum however they are two very different spellings and meanings.
