What does the slogan "no taxation without representation" mean? Can you think of some instances during your lifetime where this may also have been used

The slogan "no taxation without representation" became widely popular among the American colonists during the 18th century. It reflected the sentiment of the residents of the colonies, which felt that they didn't have the adequate representation in the British Parliament but were at the same time affected by the laws this institution passed. This ideal would eventually pave the way to the US revolutionary war.

As an example, it is common to think that the student councils of educational institutions don't have the necessary power of representation in regards to the rules imposed in these schools and how do the entity's authorities enforce them.
