请帮忙翻译速度与激情1中的一句话（最后一句I never narc'd on nobody什么意思？narc'd是什么的缩写？）

Johnny Tran: [about Jesse who is driving away] Where's he going?
Dom: He went to the car wash
Johnny Tran: Whatever. Go fetch my car!
Dom: Go fetch your car? We're not on your block any more. You better watch who you talk to like that.
Johnny Tran: [Dom walks away] TORETTO! TORETTO! SWAT came into my house, disrespected my whole family because somebody narc'd me out! And you know what? IT WAS YOU!
[Dom punches Tran and a brawl ensues]
Dom: *I never narc'd on nobody! I never narc'd on nobody!*

narc'd
英译：is when someone talk things about other person, and that things are private, personals or secrets.
中译：出卖，泄密。
nobody还有小人物，无足轻重的人的意思。

结合上下文，应该可以译为“你还不配我出卖。”

同问。。。
