A limerick is a form of poetry, especially one in five-line, predominantly anapestic meter with a strict rhyme scheme (AABBA), which is sometimes obscene with humorous intent.
The game itself is very simple: write limericks one line at a time. If you write the last line of one limerick, you also write the first line of the next one.
