Pimp Skitters Something Awful. To have an incredibly bad case of the Pimp Skitters (i.e. the runs). So bad in fact that it feels like some horrible creature is escaping your body in a violent manner.
Man, I dont' think you should eat the frito pie and banana pudding... it will give you PSSA for sure.
Pointless stupid assessment test. A test on which the government of Pennsylvania requires all students to achieve a proficient score. Since some stupids are bad at standardized tests, they are placed in "academic skills" courses. The even put the scores on your college transcript.
I have the impossible PSSA test next week.
