i back that
In a public restroom, if someone keeps saying they’ve got your back, they’re probably trying to sell you crack. They’re weird. They’re probably high.
'I got your back!' He was washing the same arm. He had crack.
'She said she had my back. She was scratching her head. She had crack.'
'He said he’d back me up. He was standing there like a weirdo. He had crack.'
