Please remember it's a very quick cheek tap, not a kiss. I'm always surprised when a foreigner does a fat lip plant on my cheek!
Regarding when the kissing between males started, reading the comments section here
http://weblogs.clari..._entre_hombres/, it seems like the Argentine posters tend to mostly agree it started in the 80's. One comment says it was definitely already started in the late 70's by the younger generation, so that buy mid 80's it was firmly entrenched.
I always thought it was from 100 years ago from Italian immigrants. I saw male-male kissing greetings (same style, one cheek tap on the right) in the south of Italy on a recent trip and assumed it came from there. I guess not.
