l cancel - When you tell someone to L cancel, you're telling them to go

When you tell someone to L cancel, you're telling them to go back in time and fix their mistake, even if they’re already dead.

You said, 'L cancel that stupid move!' I was like, 'What even is that?'

He told me to L cancel my mistake. I said, 'I’m not even alive anymore.'

She screamed, 'L cancel that shot!' I was like, 'You think I can just rewind time?'
