'ping' is a term you use over text most of the time to get someones attention.
Sarah: Hey, whats up!

Sarah: ping
Marcus: Oh hey, sorry my phone died.
'nudes' is a naked photo taken most of the time by yourself.
So when people say 'ping for nudes' or 'pfn' you text or inbox them saying 'ping' amd they will send you a nude.
