A slangy way to tell someone they're full of hot air by combining 'nah' and 'that’s cap' like a broken sandwich.
'You said you were rich? Nah, that’s cap. You still live in your mom’s basement.'
'He said he owned a car. Nah, that’s cap. He borrowed mine and forgot to return it.'
'She said she could cook. Nah, that’s cap. She burned the toast and set the kitchen on fire.'
