叫兽灰常萌i
[jiào shòu huī cháng méng i]
This nickname is used humorously. 'Professor' (called '叫兽' in playful and sometimes derogatory slang for teachers or those who act pretentiously), combines seriousness with an endearing playfulness by admitting the professor/one like that is actually very cute. The 'i' at the end could hint towards Apple products, adding another level of cuteness and a modern techy vibe to the name.
