When a new YouTube video from a popular uploader gets online and no comment has been left, people generally try to be first in commenting.
Similar to taking a girls virginity, being first to comment on a video seems to be quite thrilling to most.
Since the thrill is very high, concerned people type so quickly that they misspell "First", resulting in "Firts" or "Frist".
The end result is usually in lower case letters.
Firts!

Firt
Indefinite insult, often used in horrible rap battles on YouTube and Ebaum's to describe someone who is cartoonish, or has cartoon-like qualities. It is unknown whether or not it will offend the person it is said to.
You have a bull on your shirt... you look like a firt... from a cartoon. A coon, and it ruins like prunes... you live with racoons! Animal boom? You live in Kalamazoo.. you foo!
when one has to fart but can not due to their surroundings. So one sucks it back into their stomach.
The rumbling in your stomach is not because your hungry,you're firtin.
