An alternative term for Mexican circus music. Describes both the music and the action of listening to it.
Is derived from the oompa, oompa musical beat, inserted with various Mexican trumpets and the occasional "grito."
The beaners down the street are Oompa Loompa n' again. 5 shitty cars are parked on the lawn with fat ass women with half naked kids running around. I even saw Jorge in his wifebeater grilling fajita.
