Logical Fallacy (Bandwagon Appeal)

The logical fallacy "Bandwagon Appeal" is used when a statement suggests that an action is desirable or right because everyone is doing it. i have got to give a presentation about that and make up my own examples and wondering if you guys can help me out with that.

Also, I have an example and i want to make sure that it fits. Here at my university we have some parkings that only those who pay can get into. What some students do is that they take their friend's tag and put it on their car. so my statement would be >>Student: It is okay that i take my friend's tag sometimes, lots of people here do it. << .. anything would help =) Thank you.
