verb. Mostly used in south-east Asia. Onzzing is the level of a relationship where two people are past being friends, but aren't officially together. It's basically a relationship, minus the commitment. Sometimes it isn't discussed between two people when they are onzzing but signs of people who are onzzing are: texting everyday, knowing that they have a crush on each other, hanging out often, lots of flirting, etc.
"I see them together a lot. Are they a couple?"
"Nah, they're just onzzing."
"He's been texting me a lot lately..."
"You guys are definitely onzzing."
