An expression of mild contempt or dismissal. Usually made in response upon seeing/hearing nonsense or bullshit. This expression can also used to
mask feelings of rejection/
hurt to a snub or any other perceived/real social slight.
Dave: I sent a friend invite to Nelson over Facebook and got rejected.
Mike: pfffft. Why do you want to be
friends with Nelson for anyway? The guy was basically a total dick to you back in
high school.
Dave: Yeah I know, but people change right?
Mike:
Dude, get some self-esteem.
