nadascap
When you rip someone a new one for lying by putting 'nah' and 'that’s cap' together like a bad decision.
'You said you passed the test? Nah, that’s cap. You got a D and cried.'
'He said he was a rockstar. Nah, that’s cap. He played air guitar in a parking lot.'
'She said she had a job. Nah, that’s cap. She’s been unemployed since 2017.'
