Note: This poem doesn't really have slang in it, but the site wouldn't accept the Old English in it.
I an your angel,
your belovèd.
I am your goddess
of the night.
I am your only,
your dearest one.
I am your heavenly
delight.
I am your princess
your worshippèd.
I am your perfect
cause to fight.
I am your razor,
your bleeding slice.
I am your torture
lovely spite.
