An humiliating experience is one that makes you feel very sad or embarrassed.
When someone faces humiliation, it's often because they've been treated unfairly or made to look foolish in front of others. For example, if a student fails a test and has to stand up in front of the whole class and admit their mistakes, that could be humiliating for them. Or, imagine being left out of a social gathering by your friends - it can make you feel embarrassed and alone.
Liable to humiliate, degrade, shame or embarrass someone.
