The part(line) of a rhyme(mostly used in freestyle battles), that personally attacks the opponent. This line is a necessity to ensure your win and to please the crowd. A punchline should cause sting to a crowd or a reader. (sting is when a crowd goes OOOOOOH,,,or ohhh shitttt sonnn!!!, after hearing a punchline)
the example if from FrancisM, a goldmic.com battler and he faces jism who got raped in this battle...15/0
i put the punchlines in brackets, as you can see there are two...after these punchlines, a crowd would reply by going OOOOOOOH...these punchlines as you can see, are targetting jism's sexuality, thus making it personal...
"i call this game wid DIS-BRITISH-CRIP//wish he could "mute" or DIMINISH-LIP//((look he took "pink" as A-GAY-FETISH-TIP))//(("jism"i got more ppl on my "dick" than dresses IN-YOUR-CLOSET))//"
((the punchlines are in double brackets))
