when a male gets blueballed not because his ladyfriend is in his head or playing hard to get, put purely due to lack of experience, i.e. she has no idea what the fuck she's doing down there.
Bro #1: Bro, how was your night last night? I saw you making out with that chick...
Bro #2: Bro. I got newballed. She tried, but she was just clueless, so I told her to stop. I think she's a virgin or some shit.
Bro #1: What a newb. I'm so sorry, bro.
Bro #2, sadly: Yeah.
