The phrase hot day in Texas works online because it sums up a very specific kind of American summer heat in a few words. Texas heat is widely joked about for its intensity, dry sun and long stretches above one hundred degrees, so the line needs no explanation as a caption or reaction. Short clips built on everyday weather complaints spread easily on social video because anyone in a hot climate can reuse them for their own street, car, job site or backyard, even outside Texas itself.
