Ross and Rachel first キッス at the coffee house. And they're not even in my 上, ページのトップへ 5 couples, I just think that it's a キッス that most people know, and it was a big deal. I truly think it's iconic.
Definitely Ross/Rachel, purely because nerdy guys everywhere instantly had hope that they could be with the cheerleader they have had a crush on for years but would never have had the courage to tell her how they feel. This キッス cemented, like nearly 10 years of emotions for Ross, especially with his failed marriage, one can only imagine how he would have felt, getting to キッス the girl he loved for so long.
