Trip up means to make a mistake. For example...The girl tripped up and said the wrong answer.
Don't take it out on me means that someone should not take a problem that is not your fault, out on you...For example if your dad is mad about work, he shouldn't come home and yell at you for it, because it isn't your fault. It is a separate problem.
Playing up means exaggerating something to make it sound better then it really is. Lets say I got a 80 on my test. But I say to a friend that I did amazing on the test...In reality, I didn't do that well, but I exaggerated what I got.
Hope this helps! =]
