[Alteration of obsolete chitmunk, perhaps from Ojibwa ajidamoonˀ, red squirrel.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

1832; alteration (influenced by chipping squirrel) of earlier chitmunk, from older Ojibwe ačitamo˙nˀ ‘squirrels’ (modern ajidamóóg), literally ‘those who descend headlong’, from ačit- ‘headfirst, face-down’ (compare modern ajijibizo ‘he falls headfirst’, ajidagoojin ‘he hangs upside down’). The verb developed due to the high-pitched voices of the chipmunks in the film Alvin and the Chipmunks.
