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.

Stiff grump

When a male has a very big erection in a public place that won't go away and creates a lot of frustration, in turn it causes him to hit someone or something out of sheer anger.

"In 1st period today I had the biggest stiff grump that I hit michelle Because she was the closest thing to hit."
