A “gooseberry” (grosella o espinosa) you may know. Gooseberries are a very healthy fruit. Gooseberries grow on a gooseberry bush (grosella o espinoso).
However, sometimes mortals “play gooseberry”. This is a context where a girl and boy want to be together, and a third person, who is with them, is a nuisance because of his presence.
The boy and girl would like to be alone together. The third person is “playing gooseberry” (haciendo de carabina) and spoils the event for the boy and girl.
So, have you ever played gooseberry?
