What do they call these?

"T" stands for our tests, and how rapidly they come. "A" stands for anatomy of the teeth and all the effort that goes into remembering their every cusp, root, line angle, and furcation. "N" stands for narrowness of time left for other activities. "Y" stands for yawning from the lack of sleep on late study nights, ie... Mondays. "A" stands for the grades I better get for all this work!!!! But oh, how I love it. ;)
