caliente
A public bus (guagua) that lacks air conditioning and stops anywhere along its route to pick up or drop off passengers. The conductors often pack these vehicles to capacity to maximize fares. It is a cheaper alternative to express buses, which have air conditioning and make fewer stops. (In the Dominican Republic, a guagua is the standard term for a bus or transport van.)
It is already late and the Expresses are not running anymore, we are going to have to take a caliente.
