Pagh
A loud, near-guttural groan that comes out when you’re too lazy to form a real sentence. It can also mean ‘whatever,’ ‘no problem,’ or ‘I agree’, but only if you’re too tired to care.
Pagh! I’m not even gonna look at your failed math test.
Pagh! I’ll help you with your math homework. I’ll also cry about it later.
Pagh! I agree, but only because I’m too tired to disagree.
