papayazo 30
1º_ It is a Colombianism by "stroke of luck to notice an oversight of others or a situation beneficial to one, something unexpected that facilitates a task".

See "papaya puesta, papaya partida". 2º_ It is also, literally, a blow given with a 'papaya' ("fruit of the papayo"), or with some object called papaya, such as a grenade or throwing bomb, which gives a meaning used by South American guerrillas as "explosion of a bomb".
