grump fuck

Usually not a morning person. A grump fuck will wake up and walk straight to the coffee pot with a pinched face of discomfort due to the fact that a grump fuck is very unhappy to be out of bed. Grump fucks are not restricted to morning hours only, grump fuckieness can happen at all hours of the day. See also bitchead.

Sometimes when I wake up in the morning I look in the mirror and realize I look like a real grump fuck.
