«يِعْمِلِ الْحَبَّهْ قُبَّهْ»

The expression describes a person who takes something trivial and treats it as weighty and serious. A tiny matter, no bigger than a single grain, seed, bead, or pill, is built up in their telling until it looms as large as a domed building; the image rests on that contrast between a small round object and a great dome.

The exaggeration is usually not innocent. Blowing the small thing up gives the person grounds to feel wronged, to start a dispute, or to justify hostility toward someone else, so the saying carries a note of disapproval toward manufactured grievance.

Said critically of someone who blows a minor incident or remark out of proportion, especially when the inflated grievance seems to justify anger at another person. It characterizes the person rather than addressing them politely, so it can sound accusatory when said directly.
