Gaiban
A gaiban is someone who is so wasted they can’t stand up without holding on to something. They might even beg for help just to get to the bathroom.
My friend was a gaiban at the bar. He tried to walk but just collapsed on the floor.
I texted my brother: 'You’re a gaiban. You fell off the couch.'
At the pub, my cousin was a gaiban. He tried to talk but just said, 'I’m a gaiban, and I’m drunk.'
