¿Pero te ponés otro forro?
[Caption 36, Disputas > La Extraña Dama > 11]
But can you put on another what?
Many of you would be more familiar with the word condón or preservativo, two synonyms for forro in this context. In a dictionary, you'll find that forro more innocently means "cover, case or interior lining" of a ski jacket or waterproof luggage, say. But in an Argentine bedroom, forro usually refers to a "condom," as it does in this line from the show Disputas.
What's more, Graffiti all over Buenos Aires declares: Por amor usá forro -- "For love's sake, use a condom" -- as part of a grassroots campaign promoting safe sex. Another slogan in the fight against AIDS -- No seas forro, usá forro -- points to an alternate meaning of forro in local slang: "idiot."
An aside: X Amor is short for por amor because "x" is familiar to us all as the multiplication sign, and when you multiply in Spanish, you say dos por dos for "2 x 2." In a similar vein, Lo+Tv works for us because "2 + 2" is dos más dos. Keep your eyes open and you may notice lo+ used casually in place of lo más throughout the Spanish speaking world.
