I remember in my first job, I had a co-worker I really didn't like. He was a nice guy, but he was a complete idiot. To vent out my frustration, I talked with some closer co-workers about my problems with him. Here are some of the things I said. You might be in a similar situation of dealing with a complete idiot.

"Have you worked with Jake yet? He can't do anything right."
"The problem with Jake is that he doesn't know that he is an idiot."
"I remember helping Jake out so much, and then he stabs my back."
"I don't think he does his own work. He goes around asking everyone to do a portion of his work and says he did it all."

"If you have to work with Jake, remember the things I told you."
"Is management blind or am I being too sensitive about this?"
"I think the manager likes him because he kisses her ass all day long."

Kissing ass refers to butt kiss and brown nosing. Basically, a person who butt kisses is a person always saying good things to the manager, giving compliments, showing off in front of the manager, and doing anything possible to look good.

"The manager is blind because he is a total brown-noser."

"I can't believe this company is paying $75,000 a year for this fool."
