Someone who is acting undesirable or unlike how you want them to
act. They are either being out of
line, dumb, or going against you and pissing you off.
"Did you hear about how Kailyn from Teen Mom cheated on Jordan, why does she have to
act so damn blumzey?"
"Remember when Christian Bale went off on the
set of Batman? I used to love him, but
now I think he is blumzey as hell."
