All the feels – Chi Luu on the morphology of reaction GIFs:
Once a reaction has been identified, codified into an emoticon or emotion GIF, and then widely used and shared, it can often start to develop a morphological short form in language as users make more fluid reference to it in text. Based on the shared understanding of these terms within a speech community these phrases could become lexicalized into compounds. This appears to be happening with ‘facepalm’ and its fellow gestural neologisms, which has gone from a shorthand phrase such as ‘*face palm*’(which literally describes the gesture and might be appended to text), to the compound ‘face-palm’ (sometimes fully lexicalized into a single word ‘facepalm’) which may be used metaphorically as part of the utterance. … These compounds can gain traction outside the subculture from which it originated, and might also jump from the sphere of the written word into spoken language. These new gestural compounds such as face-palm, head-desk, side-eye, table-flip can already be observed in mainstream news publications in productive noun and verb forms.
