A small motorccycle, usually about a 110cc, used for cheap taxi service, in the Dominican Republic. It is not unusual to see one with up to five or six people one, all at the same time. They are also sometimes used instead of a pickup truck, etc., for moving large items, such as washing machines.
I was going to take a taxi to the beach, but I only had fifty pesos, so I opted for the "motoconcho".
A person who tries to start a conversation with someone, doesnt notice that the person isnt actually listening and keeps on talking, therefore is actually talking to oneself.
