This name comes from a humorous mimicking of radio call signs or military-style communication jargon. It humorously implies a playful, possibly close and frequent, interaction between 'potato' (马铃薯) and 'sweet potato' (地瓜). It conveys warmth and closeness between the individuals involved, possibly friends joking around.
