Large buttocks are pleasing to me, nor am I able to lie concerning this matter

Sir Mix-A-Lot's "(I Like) Big Butts)" "Baby's Got Back." In Latin.

magnae clunes mihi placent, nec possum de hac re mentiri.
(Large buttocks are pleasing to me, nor am I able to lie concerning this matter.)
quis enim, consortes mei, non fateatur,
(For who, colleagues, would not admit,)
cum puella incedit minore medio corpore
(Whenever a girl comes by with a rather small middle part of the body)
sub quo manifestus globus, inflammare animos
(Beneath which is an obvious spherical mass, that it inflames the spirits)
