"Hey, do we have any Chinese food left?"
"Oh crap, I was just in there getting a beer and I forget what else we have."

Use instead of the two words Fucking Ignorant. To describe an act, person, situation, etc... Anything that the user of the word finds objectionable, rude, offensive, lame or otherwise.
