a dodge patas

a dodge patas - (to get around) on foot. Definitely an expression that shows the class division in Chile. people who can't afford cars get around on foot or by public transport. So if asked how they arrived at a place they might say "a dodge pata". Since Dodge is a brandname of car, you think they might be about to tell you the type of car they arrived in, but they're making a joke of the fact that they arrived on foot (pata, actually means animal legs, but is used colloquially to refer to human legs).

Diego: Como llegaste a la casa del chamo?
Ana María: A dodge patas po, weón, como no me fuiste a buscar.

Diego: How did you get to chamo's house?
Ana María: On foot, since you didn't pick me up.
