 For example, a Mexican bus driver may ask a passenger about "la parada", which can mean both ""the stop"" and ""the erected one"".Therefore, a wary passenger should be careful not to reply, e.g., ""al tope"", which can mean ""at the speedbump"" but also ""the whole thing" or "until it stops"".When the antecedent for a pronoun is substituted for a sexual reference the simplest (cheapest) form of albures can be achieved.
