A consumer creation made by combining a fast food burger and taco. The taco is placed, with hot sauce, above the meat patty and below the top bun. Typically, they are made out of items off the "value" or "$1" menu.
"I've been burgo ever since I woke up, man; I should never have eaten all those chimichangas before bed."
"Call me back in five; I'm burgo."
