Egregious

Egregious (uh-gree-jus) means horrible, outrageous, unbelievably bad, terrible, horrendous,  or awful.

​For instance, if you asked for a 10% cost of living raise to your allowance and your parents only gave you 4%, you could tell them, "This cost of living raise to my allowance is egregious!" Then you could ask them what they intend to do about it. 

Don't be surprised, however, if they respond to you by saying something like this: "We pay for your cost of living so the burden is on us. You asking for 10% increase is egregious. You getting a 4% raise is more than generous under the circumstances."
