Which literary device is used in this poem?

for a lady i know
by countee cullen

she even thinks that up in heaven
her class lies late and snores

while poor black cherubs rise at seven
to do celestial chores.

In this poem, the author exaggerated that the lady thinks that social segregation exist in heaven. This is an exaggerated statement used by the author in order to emphasize his points.
