I had a few kids in the grade above me do that for a few years. I just ignored them - not like glared the other way and sped past, I mean really ignored them like they weren't even there - and eventually they just gave up trying. Now, at the same time, I was careful not to get caught anywhere alone with them, but that wasn't hard.
There were a couple kids in the class behind me that tried the same thing (actually my age, I was youngest in my class). They ended up trying to jump me. I can't say I beat them, but they didn't beat me, either, and after they realized I would fight back they gave up entirely, too. But I didn't let their teasing get to me until they tried something physical.
Mmm....I think this sounds too much like a standard advice wich has always been good advice but........well I would like to say with it, that if you keep ignoring, it might become a very difficult time for you. As I've seen sometimes at my school, things could get even badder than it was, because if they're really pathetic, they want to get to the point were you DO react, and to get there they might get very dirty to you, and steadily increasing.
On the other hand, if I had someone in class that was bullied, I would think off him as a freak if he would first ignore everything and then suddenly bust a hole into his sorry head, now people might get scared of you really, I MEAN THAT SERIOUS.
On another hand, seeing your discription of the guy, small and lightweight like a feather, it might just be the type of person you would LAUGH OUT IN HIS FACE WHEN HE FINNALLY GETS BEATEN UP AND BEGINS TO CRY LOL!! That would look EVEN MORE pathetic than he even was

And the timing might affect others opinion on it too, if it's the final schoolday, maybe more fellow class mates, will think you've got style

And would go home with that in mind.
That timing could also mean that many of your fellow students would go home and because it's done with such style, might tell their parents like: "Oh btw something pretty serious happened today" and that's not what you want, cause then the parents AND fellow classmates will think of you like a creep.
It's pretty much about how the rest responds to it, and that bullier could AFFECT that but eventually he is going to stop. But the rest might just begin with proceding on a whole other stage: saying that your scary. And that's pretty harsh if said seriously.
My personal help is as well as Blackbird, just look at tem lke they're absolutely CRAZY and say something like: "ey bud......what the hell is really wrong with you stupid, you should see a shrink or somethin, go bother your friends mate, if you have any*walk away shaking your head*" If said seriously and well timed, it might actually help in early stages, but not after a LOOOONNG while of bullying.
Long time bullying means more serious manners to try to counter it, sort it out quickly is one thing I would DEFINATLY ADVICE, and that's why ignoring might be a bad thing to do..
DONE, FINALLY LOL
