Critique my Workout Routine

[goodsamaritan]

Monday: Chest
Tuesday: abs
Wednesday: biceps
Thursday: triceps
Friday: Chest
Saturday: abs
Sunday: biceps

I don't care about legs. I just want to have a big upper body

Diet:
I eat twice a day because I don't have time to eat breakfast. For lunch I usually eat a hamburger or a pastrami sandwich. I now it's hgh in fat but its also high in protein and I just care about getting huge. For dinner I'll usually make a burrito or something.

I've been doing this routine for about 6 months but I still dont have really nice abs like Brad Pitt in Fight Club and I'm not that much bigger. OOT: what is wrong?
