The one that annoys me the most is when people say "man" after everything. "**** sake man" "no wit a mean man"
To be honest I say it as well sometimes, I don't think it can be helped. It's just when some ****s talking and you notice how often they say it, it's annoying as ****.
I hate that .. man! Guy across from me in work says it all the time <beeeeeeeelllllllllllll> He also says "gig" ... ****er!
people that say, "know what I'm saying" after a simple sentence. Of course I know what you are saying, I am not a complete ****** like you obviously are.
