Imho Tarantino dialogue is like this: He's trying to figure out what would be the absolute coolest thing someone might say at that precise moment but the problem is he personally is the antithesis of cool so he has no possible chance of getting it right. I suppose it appeals to other people who are socially awkward and arguably it's a successful method since a good deal of people fall into this category but it's just not stuff you would ever want to regard as authentic in any way.
Overall effect of this combination of awkwardness and worship of larger than life personae(mostly borrowed from comic books) is cheesy/corny/embarrassing to watch dialogue. No.1 rule of writing: Stick with what you know from real life, else you come off as a jock-sniffer.
