5. She is a ho

ho 这个字，也是美国年轻人把 whore 字改变而成的一种口头禅或俚语。意思是指一些年轻女人，也许因为 peer pressure 或 curiosity 或 enjoyment 的心理，随便自愿与男子免费上床。(a girl or woman gives sex freely without charge)，也就是说：She is very loose. 或 She is a loose woman (girl)。 ho 也可用复数：
    They are (were) hos.
    There are quite a few hos in high schools. 但是如果用 whore，是指妓女，男人需要付钱的。(a girl or woman is paid for sex.)

6. Catch you later！

这是年轻人说「再会」的口语。(a form to say“good乡bye”) 也就是说：现在没有时间与你交谈，以後再谈吧！(I don't have time to talk with you now, but we can talk later.) 因此，catch 就是 talk 或 contact 的意思。catch 後面，也可用其他人称代名词（him, her, them 等）
有时年轻小伙子也用：I am off. 意思就是：I am leaving now; I'll talk to you again.
(我要走了，再谈吧！)
