Whatcha gotta do is think fast of da first 2 rhymin words ya gonna use
and when one line (not bar) is over,start ta think of 2 more dat rhyme
and keep doin that.
But ta keep goin, just think of a word or two dat alotta other words rhyme to
For example:changed emcee,thang wit me,bang wit me,hang wit me,
game quickly,gang shit be,cant fit me,etc.
But remember,freestylin means "your style" so just spit your style
