The word drag comes from

Answer 1

The origin is thought to be from Victorian theatrical usage in reference to the dragging sensation of long skirts on the ground, an unfamiliar sensation to men. The usage is not found in print until the 1870s but must surely be older. Jonathon Green suggests that the gay implications did not arise until the 1920s, and that all the early citations in the Oxford English Dictionaryrefer to fancy dress.
