faded
When a stoner is so wasted they can't even pick a number out of 10, they say 'faded.' It's like they're so high they're barely holding on to reality.
'I'm faded, bro. I can't even count to 10.'
'She was faded and just kept eating Doritos like it was her life.'
'He said 'faded' and then fell asleep on the couch.'
