can someone explane the joke in the Bad video for me?

What Mjlover101 said.they ask him what he majored in.he сказал(-а) there was no majors in high school.then they asked what his minor was and they started laughing...and he's like Ты guys are sick.somebody told me 'minor' is a less icky word for d**k.so i think thats what they were laughing out.

lol..i wondered too...but idk

I think that one of MJ's Друзья asks him what his major is, thinking MJ's in college, but because he's in high school he doesn't have one so then his friend asks him what his minor is (since high school comes before college).

i have not idea, i didnt understand it eather!!!!!and im good at speaking english!!!!LOL XD
