I donnow if you'll like the idea but everyone can just rhyme with the previous 2 lines. The rhymes go 2 by 2 lines.... So i start with 2 lines and the next person writes 2 lines also [not necessarily rhyming with mine, but still with the same sense] The most imortant is that your own 2 lines should rhyme: Yo, here we blast off, commiting our crime Everybody in the boards can try something to rhyme
