This is a song about "Plaster"

I get it crackin' like the lips of a nigger, actor

Spell befell my plaster, formed forever after for laughter,

Do it with no effort, now lets effin' celebrate

When their hits are lame, fake as plaster walls, no heft or weight

Find n.a.s.a. plaster, the first draft on a ship

Of my dick, head, melon off and let it rip
