I believe chef is cool, but I'm a Cartman fan to be honest.
In my personal opinon, the coolest kid in South Park is Kyle, because he is the one that always makes the most sense and gives us viewers nice life lessons.
The "coolest character in the world" is a matter of personal opinion. My personal 'coolest character' is Roxas from the Kingdom Hearts video game series.
South Park is stupid. so why watch it.

Jack and Kate are the two coolest characters in LOST.
Some of the characteristics of the South Park character known as Timmy are that he is a handicapped young man with a bright sense of self-esteem. He is known for his enthusiastic shouting of his own name. The character is treated as an equal on South Park and he is well liked by many fans.

The voice actor for that character in South Park was Frank Welker. Although he is not directly credited for the voicing of the character, he was the one who provided the growl sounds the character made.
