Those fucking annoying people that act like their good at everything even though they dont know shit. They normally cant be proven wrong as they know everything, will try to order people about and walk all over you and act all high and mighty all the time.
They put on a show in public places and talk really loud in hope that it will draw attention to them and make people notice how "great" they are.
For guys they normally act "Big Man"
Girls tend to act liek they are super intelligent.
"Whys that prick bragging so loud i bet its not even true, their so pretentious it pisses me off!"
"how fun would it be to hang that pretentious dick up by the foot and use him as a pinata".
