Confusing Names and Probable Solution
AAP as ancronym for Aam Aadmi Party is confusing. I think calling it AAParty (आपार्टी in Hindi) is preferable to AAP (आप).
Similarly, its members/supporters may be called AAPian/s (आपाइयों या आपवाला/आपवाली).
If AAP cadres try, they can start using it on MSM. The new words may be adopted fast since AAPians is a group of young and dynamic citizens who think of the country and people.
