examplification  - Gina:  I am so irate.  I was all pumped up to ace my physics test, but then our walking rectum of a physics teacher started making that grotesque whistling sound out of his nose during the whole exam, and he weakened all of my test-taking powers.  Gah!  He gets on my nerves so bad!

Gina:  Completely.
