這些是美國俚語，只有年輕人會懂得。 american slang! jam表示一首歌，是非常slang的，特別用來講到一個hiphop song。 "that's my jam" -= 就說 "that's my song!" 意思就是 我非常喜歡那首歌，就是我的歌 ！！ bust 這裡好像 有【發出】，【發揮】的意思。a move = 一個動作。 就是跳一很靈活很厲害的舞。

My jam: Your favorite song when you hear it you go crazy. Girl thats my jam!!! Bust a move: means to make a move on a woman. eg: I'm gonna bust a move on that sexy girl or to save yourself from a awkward situation with a lady "hey did you see bob last night with that girl?" "yea he has to bust a move and get to know her"
