The spelling of "rabbit earses" is incorrect. The correct spelling would be "rabbit ears" or "rabbit's ears." The mistake likely arises from confusion over the plural form of "ears." In the English language, the plural form of "ear" is pronounced as /ɪrz/ in IPA phonetic transcription, which can be misleading when combined with other words. It is important to pay attention to grammar rules and pronunciation in order to avoid errors in spelling and communication.
The term "rabbit ears" is derived from the appearance of the television antennas that were commonly used in the past. These antennas often had two long rods that extended upward, resembling the long ears of a rabbit. They were used to improve the TV reception by picking up signals from local broadcast towers. Over time, the term "rabbit ears" became synonymous with television antennas or antenna-like objects used for better reception. The plural form "rabbit earses" is not a standard term and seems to be a playful or non-standard way of referring to multiple "rabbit ears" antennas.
