The gas station pump sign that shows up literally when texting about a road trip stop, but online it's also shorthand for being drained — 'need to refuel' energy, tacked onto a selfie after an exhausting week. Emoji since the very first Unicode 6.0 set in 2010, it's one of the plainest 'transport-ground' icons and rarely gets reinterpreted, which is rare for an emoji this old.
