a word used generally when referring to any male. can be used in the place of "man", "son", "dude" and so on. But there should never be a "that" in front of neph, often people make this mistake.
This rule is like the a/an rule in enlish class. You might say "give me a apple" rather than the correct alternative "give me an apple", but you can't get away with saying something like "give me an dollar". This sounds stupid, as does "look at that neph".

*neph is the short version of nephew
1. Call the ambulance or sumthin, neph just got hit by a big ass truck.

2. Neph, you aight?

3. Neph, is very similar to dude, but unlike dude, one shouldn't say sumthin like "i know that neph"...it just doesn't sound right. Just say "i know neph". One should also avoid saying things like "which neph" as a response, just say "who?" or sumthin like "Neph, who the fuck you talkin bout?"

4. Neph not as patient as I am, John tried to cock block (see cock blockin/cock blocking) when he was about to hit that chic off, and he just beat John ass yo!

5. Yo son, look at neph in the spandex.

aggitating the rest of the audience that are all too frigid to come forward as there are three youths at the front nephing.
