azaroso
A person who brings bad luck or bad vibes to a plan by constantly mentioning what could go wrong. It describes a jinx or someone whose negativity or pessimistic predictions supposedly cause the failure of an event (in the Dominican Republic, this act of jinxing is called azara).
On the way to the beach: Azaroso: Luis, did you fix all that crap on the car? Because you know this thing breaks down every second. Luis: You are always at it... This is all good, chill out man. Azaroso: No, just in case, you know... (Sound of a tire blowing out, they have to pull over). Luis: AZAROSO, you damn bastard, shit... what a mess with you man. You always azaras the whole thing, one cannot do anything with you, you popped that tire and I do not have a spare. The trip is ruined.
