Sometimes known as "worming" – which somehow makes this whole thing worse – oculolinctus is being blamed for a significant rise in Japanese cases of conjunctivitis and eye-chlamydia, which is actually a thing. It's apparently seen as a new second-base; the thing you graduate to when kissing gets boring.
I think I did that @15 with my first GF. I'm not seeing it (no pun intended) as any worse than licking a persons genitalia really..
You never kissed eyes when you were a teenager? I did. But of course it was with our eyelids CLOSED!
You know, I just got back from two weeks in Japan and it's not nearly as weird as the internet would have you believe. I didn't even see a single vending machine selling anything other than drinks. A few of them were beer vending machines but those are just awesome, not weird. I'm beginning to think it's all a big conspiracy to make Americans feel better about themselves.
Butterfly kisses? When you flap your eye lashes together.
