If you are "sick and tired" of something, you have done or seen it too much and now it is boring or unpleasant for you - and you wish it would end. So your phrase means that you have been tired and sick all of the time, so you wish it would end. You can use "I'm sick and tired of..." anything. For example: I'm sick and tired of Big Macs for dinner.

haha,thanks~

Obviously used to be funny.
