When we say that a situation is a "storm in a teacup", we mean that it is a small or insignificant situation that has been blown out of proportion. Some synonyms for this phrase include "much ado about nothing", "a tempest in a teapot", and "making a mountain out of a molehill". When people make a big deal out of something trivial, they might also be described as "making a fuss", "causing a commotion", or "creating drama". It's important to remember that although it can be frustrating when people make a big deal out of nothing, it is often best to remain calm and not let the situation escalate further.
