WHAT ARE LINES AND BARS???

first off, dont post in all caps. lines are like this:
this is a line//
of a simple rhyme//
like a wack line//
see that? that was 3 lines

this is a bar:
welcome to this bar//
you hope to come far//

rappin me is silly//
coz yo got a small willy//
that was two bars. two lines = one bar. that help? oh yeah dont use my wack lines as examples, two year olds rap better than that

thank you for that lab rat, i flow better than that with a cock in my mouth..

i hope we meet in battle so u can clown me for bein gay

and if i ever post hate in ur forum ever again Kapz. you will be pissed off and be forced to have u and ur crew give me a few loses

thank you
