What is Mcpeek?
1.
Used as a greeting to a friend, usually a shout used to get anothers attention.
You see your friend Bryan on the street and yell "MCPEEK!!!"
2.
A loud exhortation paying homage to a fat and bald 40 year old who attends high school.
So, I saw McPeek walking down the hall and I just had to yell, "McPeek!"
