Best Answer - Chosen by Asker:
As a former boy myself, let me give you a first-hand response.
At this age (usually bout the time puberty sets in) boys tend to be more aggressive due to hormonal surges (testosterone) in preparation of eventual mating. Therefore, boys become very peer aware and tend to "out-do" each other as a form of mating rivalry.
If a boy does something nasty, and he handles it in front of his peers, he views himself as being more "brave" than the others, and therefore more desirable toward females.
As far as the "gross" things that boys do, well, it's just darned fun!
(and for the shock value!)
