There's nothing like expressing your love for a significant other by slobbering in her retina.

"Oculolinctus" — otherwise known as eyeball licking — is a phenomenon gaining attention in Japan, as young couples find new ways to show their affection. However, such cringe-worthy amorous acts could come at a cost.
