Abbreviation (rev.)

In our life, or say career life, we learn abbreviation. If you are a computer geek, you definitely can call out a series of this like CPU, AVI, DRAM ( since I am not, only able to call out couple), If you a car guy, you should able to call out like CV joint, HP, RPM, DOHC, SVT, STi, SLK, M3, R, S, CL, GTR, MR (This little alphabet really make a huge different in performance, but forsure not those emblems you add in your car bumper, for example "Limited Edition", " Turbo")...Recently I have learned from my new work, AQL, CPK, MRB, DCAR, 5s... and also from friend, SHIT, MHO, LOL... H1B, EB1, OPT, 481, 285?? Damn! If you know this, you are imigrant. Or you must be an attorney or some sort.
Anyway, today I feel like share some cool one, RNB, KNN, CCB, KNNBCCB, HLK, HKS... damn... feel like want to say this loud...don't understand this? Check with Mr. T.
