rusty monkey 

Drinking down a forty ounce alcoholic beverage to a desired level (typically the bottom of the cone), then topping off your forty with Mad Dog 20/20. The same concept as a brass monkey, but a lot more disgusting.

Jose: That beezy was on my dick last night!

Juan: Well no wonder, she had herself a rusty monkey
