Whilst performing a blumpkin, the individual exercising fellatio wears a sombrero loaded with chips and queso dip allowing the receiving party to enjoy simultaneous south of the border pleasures.

Alternative; Blumpkin con Salsa
While evacuating his bowels, Paco enjoyed the Blumpkin con Queso his girlfriend so selflessly provided.

Get the Blumpkin con Queso mug.
Similar to a normal blumpkin - a la getting dome while taking a dump- however with a very important twist...

Once in the process of gettin dome, you must procure a sombrero and put it on the girl giving you dome. Then push in the center of the sombrero and fill in the dent with nacho cheese, fill the brim with tostidos, then enjoy the greatest gift on God's world.
Mike: Yo nick you look spent as hell, and why do you have nacho cheese all over ur face?

Nick: Cuz i just got a blumpkin con queso mothafucka!!!!
